Hard drive too long to detect solution

Almost two years ago, my Pentium 2 333Mhz (now upgraded to 400 Mhz) CPU was not able to detect my 40GB Seagate harddisk when I decided to flash my BIOS. The solution I found was instead of letting my mobo do an autodetection I assigned the values my self. The following are the HDD’s head,sectors/tracks and cylinders numbers for different hard disk capacity. You may ignore the crossed parts. As you may have noticed this was taken from a multiple linux installed PC.

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 1 60801 488384001 83 Linux

Disk /dev/hdc: 40.9 GB, 40982151168 bytes
255 heads, 63 sectors/track, 4982 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hdc1 1 4863 39062016 83 Linux
/dev/hdc2 4864 4982 955867+ 82 Linux swap

Disk /dev/hdd: 120.0 BG, 120060444672 bytes
16 heads, 63 sectors/track, 232632 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

Device Boot Start End Blocks Id System
/dev/hdd1 1 232632 117246496+ 83 Linux

disk /dev/hdb: 30.7 GB, 30735581184 bytes
255 heads, 63 sectors/track, 3736 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hdb1 * 1 3736 30009388+ 83 Linux
