How To Get Linux to Work with a Disk

If your disk is an IDE or EIDE drive, you should read the file
/usr/src/linux/drivers/block/README.ide (part of the Linux kernel
source code). This README contains many helpful hints about IDE
drives. Many modern IDE controllers do translation between `physical'
cylinders/heads/sectors, and `logical' ones.

SCSI disks are accessed by linear block numbers. The BIOS invents some
`logical' cylinder/head/sector fiction to support DOS.

Older IBM PC-compatible BIOS's will usually not be able to access
partitions which extend beyond 1024 logical cylinders, and will make
booting a Linux kernel from such partitions using LILO problematic at
best.

You can still use such partitions for Linux or other operating systems
that access the controller directly.
