from flipping burgers to boot the etch-a-sketch and scribble out:
does anyone know how to configure a computer so when i turn it on, it doesnt automattically start up windows? as in it starts in ms-dos, and just leaves it at that? im running windows xp, if it helps. thanks in advance.
Install DOS?
...do you really install DOS though? I mean, you can run DOS...but it
doesn't really need "installing" per se.
Actually, yes you do. If you have a blank hard drive, not only would you need to format it, in order for it to be a bootable drive, you also need to place the "system" files on it. You don't simply copy those files to the drive in question. There are specific steps to put those files on the blank drive such that the files end up in the correct place to make the drive bootable. You can either use the format command or the sys command, like thus: "format drive: /s" or "sys drive:" (where drive: is the drive letter of the blank drive). Which could be considered as "installing DOS" (for at least the bootup files for it).
Actually that's not entirely true. While it is common practice to use
the syntax: format c: /s when creating a bootable HDD, you don't
necessarily need to use /s to create the system files.
The common files found on a bootable drive are:
command.com (+R +A)
io.sys (+R +S +H)
msdos.sys (+R +A +S +H)
And in some cases this will also include (even though it's not
necessary unless you're using a compressed drive):
drvspace.bin (+R +S +H)
dblspace.bin (+R +S +H)
As long as you have the three main files io.sys, msdos.sys and
command.com set with the proper attributes the HDD will still be
bootable. But it is necessary to make sure that you have the proper
versions of those files OS that you're installing. IOW, you can't use
those files from Windows XP or lower if you're just using MS-DOS. They
aren't compatible and you'll be back at square one all over again.
But it would be rather silly to do that on a computer that is otherwise already operating perfectly fine.
Adam, go to Google and try searching on the phrase "xp boot to dos". You'll get tons of hits. One of those will be the answer you're looking for and will probably explain things a lot nicer than I can.
My advice would be if he wants to install, say, MS-DOS 6.22, he'll
have to buy a HDD that's at least 2 GB or less. Unless he wants to
create separate drive letters. I wouldn't go any higher than 4 GB
though. (The HDD will still have to be broken down to smaller
partitions to accommodate for the size of the drive under 6.22 if the
HDD is more than 2 GB in size.)
won't work. Copying files doesn't set up track 0 properly.
It should work after the HDD has been formatted for that OS. Once it's
formatted then copy the three files and go from there.
OSes tested: MS-DOS 6.22, Windows 9x.
There's only one small problem. Windows XP (Both Home and Pro) won't
have format.com, sys.com or fdisk.exe in C:\Windows\Command. I guess
M$ decided they were no longer needed. So I'm not sure of a way around
that without having to use maybe format.com from Windows 98 and then
upgrading the OS to XP.
I keep a few floppy images around (including DOS 7) that I write to floppy using rawwrite. Maybe you can't actually do a DOS "format" but you can use this trick to create a "boot floppy" from XP. I actually burn them to CD using ISO magic more often than to floppy.
To format a hard drive would first require booting from a floppy or CD.
