s LBA-28 kernel code. Trebe LBA-48 support ... ili new ATA standard....
The old ATA standard describes how to address a sector on an IDE disk using 28
bits (8 bits for the sector, 4 for the head, 16 for the cylinder). This means
that an IDE disk can have at most 2^28 addressable sectors With 512-byte
sectors this is 2^37 bytes, that is, 137.4 GB.
The ATA-6 standard includes a specification how to address past this 2^28
sector boundary. The new standard allows addressing of 2^48 sectors. There is
support in recent Linux kernels that have incorporated Andre Hedrick's IDE
patch, for example 2.4.18-pre7-ac3 and 2.5.3.
Maxtor sells 160 GB IDE disks since Fall 2001. An old kernel will treat such
disks as 137.4 GB disks.

http://www.ans.pl/ide/testing/ide-backport.txt
o backport from linux-2.4.17+ide.2.4.16.12102001.patch:
ide-disk.c - ver 1.12:
LBA48 addressing code is ready. It may work.
Don't have required hardware to test it.
