hey everybody chris here again welcomeback to the channelalways good to have you with us so todayi'm finally getting around to a videothat i've been wanting to make for awhilewe're gonna boot ms-dos but not in theway that you normally seeyou see when you go to boot ms-dos youmayuse a simple floppy disk oryou may boot it up using a hard disktoday we're going to use neither ofthose technologiesand we're going to boot up over thenetwork using my 3com etherlink 3 cardand a lan works boot rom so first we'regoing to cover a preconditionwhere we talk about the network settingswe need for the network cardto conduct this procedure and then i'mgoing to show you the setupfor my windows nt server running in avirtual machineand yes our server today is completelyvirtualwe'll then have a bonus round where weconfigure ourms-dos session to use tcp ipfor land manager support and thenfinally i'll give you my thoughtsin the wrap-up so without further adolet's goso there is one precondition we need toworry about when we start up and get tothis screen on the client we can do actrlalt b to get to this configurationscreenand we need to make sure the bootprotocol is set torpl and we do have several options withthislan works tri-rom including boot p somenetwork options dhcpetc but it needs to be set to rplfor default boot you can either makethis network or a localdeciding if it will boot to the networkor if it will boot localwhen starting up the machine so that'syour choice i choselocalso to configure remote boot first we'regoing to set up an ntserver virtual machine so here you cansee i've gone into virtualbox andselected newand i typed in windows nt server set thememory to256 megabytes and we're going to createa virtual hard disk of typevmdk and the defaults are fine so we'lljust go ahead and click on through thistwo gigabytes is great and we have avirtual machinenow we're going to configure the networkcardto bridge to a wired network cardif you bridge to wireless this will notworkit needs to be wired so i will choose myreal techcard there and click ok and we are nowbridged to a wired cardgood let's go ahead and start upand as we start up we will be promptedfor an isoi'm going to put the windows nt serverisointo the virtual cd-rom drive and fromthere we can start theinstallation procedure of nt 4.0 server[Music]so here we can see nt doing its nicestartupand we get to this screen and compressenter and then enteragain and then we can press c tocontinue setupsaying we don't have a hard drive set uppage down page down page down a milliontimes and f8 to agreeof course read all that first enter onthis screen to continuec to create a partition on this screenenter to choose the default sizeand then enter to go ahead and selectformatand then arrow down to ntfs and fromthere your nt initial setup is prettymuch completeenter to choose the win nt directory andonce againenter to allow an exhaustive disk testnot necessary on a virtual machine butit doesn't hurtcool so from there nt will finish itsinitial setupwe can go ahead and remove the disk fromthe drive as it saysand reboot by pressing enter and thenpressenter there and it will go ahead and dosomework reboot and then it will continuethe installation but of course you needto put thecd back into the drive so go ahead anddo thatso we'll do that here and then we canclick ok and the processwill continue on very good so a littlebit of lightning round but that's finefrom here we just go through the rest ofthe steps we can do our nextput in our name and you are forced toput in an organizationsetup cannot continue without it so putsomething in for thatand then from here i just set mylicenses to five per serverand then click next put in a computername i just called thisntboot and that works for me and it'sgoing to be a standalone server so wecan selectthat option as well moving on i'm notputting an administrator password inand i'm not creating a repair diskthe default components are fine so we'llclick next on thatand then next to do the rest of setupwe will participate on a network so nexti don't want to install microsoftinternet information services or serversonext we can do a start search to findour adapters it will find itinstantaneouslynext and then we need to add someprotocols or a protocol so select fromlist and choosedlc protocol that's needed for remotebootand enable netbui for some reason it'snot enabled but it's there go figureokay on this screen we need to add theremote boot service so we can scrolldown just a little bit in the list thereand find itand we can select it and click okand we will have remote boot serviceready to installgreat so go ahead and click next you cansee everything is selected so you can goahead and click nextand things will start to happen once weclick next herethere it goes okay so some defaultsettings for the network cardjust to continue there's nothing to dohere and then yes to allowthe hcp that's great andalso continue for the location for rplwe will certainly become familiar withthat later and then we've got this goofything where we actually have to pointthe path to something it already knowsaboutexcept for you can't just put the pathin you have to put the drive letter intooi don't understand this but whateverit's nt what do you expect so continueon at that pointand it will finish out[Music]from there we get this screen we can hitnext and then next againand then we can check everything herecomputer name and work group are fineand then finish to finish set upand we can choose a time zone i just usethe arrow keys and i go backwardsbecause i'm minus 500it's just easier than going all the wayaround the world i don't know if youcould anywayso there we've got that for the displaywe're just going to leave it alone we'renot going to do anything fancyi'm not even going to try to make itbetter 640x480 is fineit will continue to do its thing and askto show us the log filebecause it failed to create a swap fileor somethingwhatever that's fine just click closeit'll work finefrom here we can restart so let's goahead and remove thecd from the drive so it doesn't try andboot on it andwe can click on restart so all goodstuffalmost done there's a couple more thingswe need to do after i go ahead andrestart hereso we can log in by doing control deletesince control is the hostkey and that will simulate a control altdelete by doing control deleteokay at this point we get to install ntservice pack 3 and you guessed it weneed to put the cd back in the driveagain if i had a nickel for every timewe did that during this installationdid anybody keep count anyway back in itgoesand we can expand the screen and clickokand it brings up this nice screen toobecause it detected the diskjust close it if you can and then fromthereclick ok and then from there clicknext and click yes to agreeand then next again and yes no we don'tneed to create an uninstall directory wehave nothing to save it's a brand newinstallation next and finishand it will do its thing rather quicklyafter all thati go ahead and keep the higher gradesecurity files so i hit skip for thatit doesn't really matter for what we'redoing okayokay so now we can go ahead and removethe disk from the driveand restart and yeah great i'm doingthis quicklyon restart it's going to pop up aninstaller just clickuncheck the check box and click exit andthen from there it will not bother youever againso good all right because there'snothing that we care about there okayfinally now we can do something so if wego to settingsand control panel the first thing we'regoing to do is enablethe remote service the remote bootservice because it's not enabled bydefault it's set to be manual and that'sby designso we can go in there and find it and wecan double click on itand then change it to automatic andclick okand then from there i'm going to clickstart so that we can start it for thefirst timeand then on subsequent reboots it willstart automagicallycool so now we can go ahead andconfigureto remote boot ms-dos and i'm followingthis nice article hereit's a microsoft article somebody hasarchived them thank you very very muchthis is very good and very helpful so wewill pretty much follow thisso without further ado here we goso what we want to do is run the remoteboot manager which should be accessibleunder programsadministrative tools remote boot managerbut it's notthere's some sort of a bug i didn't takethe time to find out whywhen what or where what i did insteadwas go to drive cand then go to when nt and then go tosystem 32and then just find it find itsexecutable because it's in there underthe rsso we can find that and there it isrplmgrand right click on it and say createshortcutthat'll create a shortcut i'm going todrag that to the desktopand that's how we're going to launch ittoday there's probably a fix for iton the administrative menu but i'm notgoing to worry about it okayso with that going we can then go andlook at the rpl directory and the firststep in the directions is make sure thatrpl files is shared it is notthere's no blue hand under it so i'mgoing to load the rplmanager and it's going to give us awarning that we don't have any profilesthat'sfine what we can do is go up toconfigure and sayfix security and then yes and that willfix itand for good measure i'm also going todo a configureand check configurations though i cantell you you don't need tobut it doesn't hurt anything right rightcoollet's refresh this little screen overhere and if we do thatby going to view and refresh we will seewe now have a magic blue little hand ori guess a blue sleeve with a white handso that is now shared and fixed goodstep one completealright so now step two is to copyyour dos files over the first thing i'mgoing to dois log on as administrator because we'regoing to be connecting to thisnt share and we have to have the rightusernamefrom there we can map ntboot rpl filesto drivem on our client machine and this isactually not the real client machinethis is just another virtual machine ihaveit doesn't matter the key thing is weneed to be able to getdos 6221 so by going to bin files.622we're going to copy our ms-dos directoryto thislocation and that will give us all ofthe dos programs that we needexcellent the next thing we need to dois actually copy iosisand ms-dos this but in order to findthem on our drive we need to make themunhiddenand unsystem well at least unhidden sowe can do that for both files and thenthey will be available to copyto the volume so there we go there'sfile number oneand here we go here's file number twoand once done let's go ahead and run atrib to set them backso that this virtual machine willactually boot againi don't think it'll boot if they're notsystem and maybe not hidden i haven'ttried it but i don't think it would workperfect with that we can go configureand check configurations and it willactually generatewhat we need so that we can create aprofile so now we can go remote boot newprofile and go to configurations and wehave ados 622 3com etherlink3 profileperfect so let's go ahead and name itaccordinglynice long descriptive name okay and wenow have a profilethat's great so at this point we canactually startbooting the system and it will put anentryinto the table on the nt server when wehit f5 that entry appearshowever we have not authorized orassigned it to a profileso we can convert the adapter and thengo down and choose the workstationprofile we care about and give it a nameso i'm just going to call it 486 dx4 andwe have our default profile selectedso there you have it now if we returnback to the systemit will catch when to this and it willcontinue the boot process and it willnow forever bootand it's asking us for our username andpassword we did not set oneso we can just wait for that to timeoutand look at thatwe're now booting ms-dos isn't thatcool all right so we have a nice cprompt we can explore a little bit let'slook aroundwe'll see a variety of files we have anice data directory where we can putdata ini'll go ahead and edit a test file andput a line in there just to show thatkind of cool we can save this in thislocationvery nice that said there are somelocations where we can't save filesso i'm going to change into the bindirectory or at least one of them herethe bin b directory and if we go thereand try to put a file it's going to beread only but we'll give it a shot justso you can seeso i cannot save this file in here i geta path file access errorof course i'll try it twice because whynot and once againa path file access error so let's getout of hereso the other thing i'm curious about isif we edit autoexet batwill the change be persisted through areboot so we can go to the bottom of thefile hereand go ahead and add a line we'll sayecho will thischange be savedafter reboot and we'll just go ahead andsave the file and let's go ahead andrebootand lo and behold it does it echoed outto the console sothe change was saved cool so let'sexplore what that looks like a littlebitif we go into the rpl files and machinesthe first thing we'll go look atis the data directory and we can seethere's our testfile so it got saved within thehierarchy of rpl filesthat exists for remote boot we can evenmake a copy of this file if so desiredand then if we return back to the dosprompt and do a dirwe can see it's there no reboot wasnecessary it was there immediately whichis actually a pretty cool featurenow as far as deciding which files arewherewhich files are editable we have to lookat this fit fileand if we look at the fit file recallearlier that we tried to savefiles to a bin directory and if wescroll down here a little bit we can seethere are some shared binary filesin the bin r and bin b directories andthose directories are noteditable however there's a whole sectionfor machine writable filesincluding the data directory and a workstay directoryas well so that's how we were able toeither save or access filesand it explains the mappings betweenwhere files actually live within thewindows nt 4.0 structureas compared to how they get served toyour remote bootclientsnext up it's time for the bonus roundwhat we're going to dois configure tcpipfor our dos session and the reason iwant to do this is my raspberry pi hasfiles that are accessible but only viatcpipfile sharing over smb so i apologize fornot showing it but what i have doneis to make an identical copy of theprofileand named it tcp dash d622elink3you can see that there at the bottom ofthe screen so now what we're going to dois make some modifications to the bootblockfor all three com etherlink 3 cardsso i'm going to go in and modify thisdos bb file that you see hereand this is going to be for all dosconfigurations that use this particularcardand we're going to uncomment one linethat tcpdrive dot dos line so we uncomment thatand then we can go ahead and save thefile and that's going to be one driverthat we need in order to make this workso excellent okay let's go ahead andsave thatthe next thing we're going to do isactually modify this new profile that wemadeso i'll navigate back and go to the rplfiles directoryand then we can go to profiles and findour profile there on the rightso we're going to go into thisautoexec.bat file and uncomment threelinesfirst this umb.com line that you seehereand second this load tcpip lineand finally this nmtsr lineand then we can go ahead and saveautoexec.batand next we're going to load config sysbut firstlet's go ahead and say view options andmake sure when you go to view that youhave all the hidden files shown i'vealready done this this is not the ntdefaultso now we can see config sys and we cango in and editit and go down to notepad to choose aneditorand we're going to make a few changesall we really have to do is uncommentthe last linebut i also like emm386 to run and i likehyman's sister run without actuallydoing a memory testso i'm gonna turn off that and thenfinally the only thing we have to do isuncomment that last line so there youhave itgreat we can save this out and while i'mthinking about iti'm gonna go modify the other profiletooso that i have emm386 and high memphisnot testing memory there you golightning round on that perfect okayso at this point we are going to switchthe profile out iclicked on 486 dx4 i can come down tothe workstation profilechange it to tcp and we click okthat easy now when we reboot we can seeall the tcp goodnessand we can also map a drive to ourraspberrypi and that will work flawlessly so nowdrive z is mappedso let's have some fun i'll go to thedata directory i'm going to copy wordperfect 5.1 off of the raspberry pionto this nice booted system so we cango ahead and do thati'll grab that and then we will be ableto see what we've got memory wise andwe'll just go ahead and launch iti do want to show what we have memorywise and you can see that 188k ofconventional memory is usedtcp is a hog but we can launch wordperfect everything looks goodgreat so at this point i'm actuallygoing to shut downand switch over to the other profile butbased upon how files work hereour wordperfect51 should still be inplace as we reboot here and we check ourmemory first you can see we are nowusing 100kless and we can go to the data directorywp51 and run wordperfect withoutany other changes so that's pretty cooland of course this does require sysadminchanges so if you wanted to actuallymake this more configurable you can seei've modified config system auto execbatto have a nice dos menu that's what thisis all about it's definitely an optionand then when we go to boot we canchoose whether or not we want tcpiprunningand whether or not we want to use thatextra oh what was it 100 kilobytes ofmemory or not soit's nice to have choices and if we dothings this way we're not dependent uponthe system administrator to switchprofiles for us so that works out rathernice[Music]all right well that's what i had for youtoday hope you enjoyed iti found this to be a pretty slicktechnology actuallyi thought it was pretty cool i liked howdynamic it waswhen we added new files and theconfigurability optionsit definitely gets a thumbs up in mybooki guess it's a little bit sad or maybeit's a good thingthat it got supplanted by othertechnologies that came laterfor example terminal server technologiesnowit is fair to say though that thistechnology was usedfor windows 95 as well and i'll beshowcasing thatin a future video i wanted to give ashout out to andy proctor who gave theidea for thisvideo series in particular the 95 videothat we'll be seeing in the futuredefinitely subscribe to the channel sothat you can see when that video comesoutring that notification bell and you'llknow for surealso if you like what you saw today i'dappreciate if you gave us a thumbs upif not consider sending me a strongmessage by pressing that thumbs downbuttontwice as always it's been great havingyou along for the journeyand i look forward to seeing you nexttime but until thenbye for now[Music]you
