Hi. I have an old linux 2.4 box on an Abit BX6r2 (440BX) motherboard, PII-450,
UDMA/33. Can I buy a new 500GB or 750GB ATA-100 HD and use the full drive
even if the motherboard bios is probably limited to 120 gb (this is what I've
read)?

I've been web searching, and LBA-48 related comments come up, but I don't know
if this will be a limit or not. I can't find a definitive answer.

Only the boot drive's size is important.
If you use such a big drive as you first (only ?) drive, there are
solutions. But They're usually very messy.


I have a little old server, a P-II 350 MHz. It has a bios-limit too, 32 GB I
think. So what I did was:

Hardware
- put in a supported, smaller, drive as first HD (I used a 20 GB)
- put the bigger one, as second drive, tell bios there is no second drive

Bios
- set up first drive normally
- set second HD to 'none' (no drive present)

Linux install
- set / and swap on first HD
(plenty space, I copied my SUSE install DVD on it)
- set /home on large HD

The bios will find the first drive and boot correctly from it.
Linux will find both drives.


Good luck.
