Subject: Debian specific Partition problme

Dear Manoj/Sudhakar
I have posted this query earlier on the linux-india list, I found no
replies.
I am very curious to know the reason for this behaviour of fdisk program.
Could you find out this from your friends at debian.org about it?
the problme is:
I have encountered a peculiar problem on a debian (2.1). The system
has a 9.1 UltraWide SCSI disk (seagate make). When I do `fdisk' it
shows the following:
studio:/two# fdisk /dev/sdb
The number of cylinders for this disk is set to 8683.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
Command (m for help): p
Disk /dev/sdb: 64 heads, 32 sectors, 8683 cylinders
Units = cylinders of 2048 * 512 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 8 8676 8875912+ f Win95 Extended (LBA)
Partition 1 does not end on cylinder boundary:
phys=(1023, 254, 63) should be (1023, 63, 32)
/dev/sdb5 8 965 979933+ 83 Linux native
/dev/sdb6 965 1083 120456 82 Linux swap
/dev/sdb7 1083 4903 3911796 83 Linux native
/dev/sdb8 4903 8676 3863601 83 Linux native
As you notice the number of cylinders are shown to be 8693, too large to
make lilo work. Obviously I failed to make the machine boot linux, except
through a boot floppy. Otherwise there are no problems during running.
However, what surprised me was when I tried (on the same harddisk) using
SuSe 6.2, and Redhat 6.0, the out put of fdisk shows entirely different.
They show only 1106 cylinders. This time lilo also works fine.
I thought the fdisk program is same across different distros.
Why does this happen? Any clues?
