Install DOS?
...do you really install DOS though? I mean, you can run DOS...but it
doesn't really need "installing" per se.
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.)
