On that matter, I get a warning from LILO wrt cyls and stuff: 07:47 spectre:~ # cat /proc/ide/hda/geometry physical 16383/16/63 logical 65535/16/63 07:58 spectre:~ # lilo Warning: Kernel & BIOS return differing head/sector geometries for device 0x80 Kernel: 65535 cylinders, 16 heads, 63 sectors BIOS: 1023 cylinders, 255 heads, 63 sectors Added linux * 07:59 spectre:~ # fdisk -l Disk /dev/hda: 40.9 GB, 40982151168 bytes 255 heads, 63 sectors/track, 4982 cylinders All of these numbers are virtual, since CHS is not really used anymore, as we know. But, which of these fake CHS values (16383/16/63 | 65535/16/63 | 1023/255/63) is the right one? 255/63/4982 is another matter, since it [almost] matches the actual size of the disk while the other three are just "for the bios".
