Since someone already responded on how to *possibly* format this drive,=
I can supply some quick specs.

Maybe this will be useful to some of you out there. Also, I don't mean=
to be off topic myself, but I know way=20
more about hardware than about Linux, so bear with me. I've "only" bee=
n using some form of Linux for about=20
5-7 months.

Yeah, you would need to have the drive formatted first, then you fdisk =
it, and format it. But could someone tell=20
me how to format my st225 with the minix-fs? I downloaded the diskimag=
es from mit, but they only recognize=20
/dev/fd0 as root, and not my other devices.

The PCs/XTs and clones NEVER had a clock calandar like ATs and above, o=
r even CMOS memory for BIOS=20
settings. I don't know if anyone ever offered a clock chip on board fo=
r a 8086/8088 machine, but I doubt it. =20
Anyways, you can probably pick up a card at some surplus places for abo=
ut 5 bucks, with clock/calandar,=20
serial, parallel, floppy, and sometimes video. I have one card like th=
at maybe without floppy, but with video. If=20
anyone wants, privately email me and I will give you my computer dealer=
's email address: he sells those=20
multipurpose cards (no video though).

Same here. But if anyone has anymore hardware questions, please ask me=
, and in return, teach me about C=20
and compiling the source code for ELKS and its utils.
