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 had similar problems, but longer ago, with old Pentium
machines. I think the MB limitation was 8GB, but my disk
was much bigger. The MB, whenever tried to find the disk,
hanged. So I figured out the geometry of the disk (good
chance it is written on it), and simply reduced the cylinder
count, so the apparent disk size became less than 8GB. I
entered this info into the BIOS by hand. The BIOS was now
happy, and it booted the computer. I placed (IIRC) a small
partition at the beginning, /boot/, and then the rest was
everything else. Linux will recognize your disk.
Important, keep the head/sector count. Change (reduce) only
the cylinder count.
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.
Brrr. I didn't mess with the LBA. I simply lied to the BIOS
about the cylinder count, to keep it under its limit, and
the rest was handled by Linux.
