Well how to put this:
The older Award bioses use 32bit signed variable when calculating
and telling the capacity of disk, others use ABS(value) kind of function
to get negative numbers positive, others overrun the counter,
and that is limited to 2G, so 2.5G is showed as about 500M and
example: My 2.58G Bigfoot shows as 462M on one machine and as -1.7G on
(under BIOS, Linux sees the whole disk perfectly)
some implementations show negative capacity, BUT if the BIOS indeed
knows the cyls/heads/sects correctly, and You can turn on LBA
translation in BIOS (It is possible in my Asus PVI486SP3)
and the disk is translated to the operatingsystem correctly, but
without LBA translation destroy the MBR and/or FAT after 1024th cylinder
is filled with something real (as opposed to formatting only).
following is divided for PC-DOS5.0 followers vs real operatingsystems
with LBA on:
opsyses like Win95 and other MSdoses can Fdisk an 2G partition and
an 400+Meg partition.
If You use one of the real operatingsystems
turn LBA Off (use normal or large translation)
boot from bootable Floppy with Opsys installation Tape/CD/server
available and install the thing using Ext2FS or HPFS or NTFS
depending on the operating system
P.S. all info now on the disk will naturally be wiped off in this
