by Hi.
First of all a simple question: Do I have to pass the *physical* or the
*logical* geometry with the "hdc=X,Y,Z" - kernel - parameter?
I think I have to use the *logical* geometry... but what about the
phyiscal one? - Can I tell the kernel somehow about them?
Now about my hdd:
I've got a harddisc with the following geometry:
The manufacturer (IBM) says in the models datasheeet:
User cylinders (physical): 27724
Data heads (physical): 6
Data disks: 3
On the harddisk itself I found the following:
CHS=16383/16/63
LBA: 90 069 840 sectors
And 90069840 / (16*63) = 89355
If I pass "hdc=16383,16,63" with "append=" in the lilo.conf to my 2.2.14
kernel a "cat /proc/ide/hdc/geometry" says:
physical geometry: 89355,16,63
logical geometry: 16383,16,63
And if I pass "hdc=89355,255,63" with "append=" in the lilo.conf to my
2.2.14-kernel the "cat /proc/ide/hdc/geometry"-command says:
physical geometry: 89355,16,63
logical geometry: 89355,255,63
But I think it should look like:
physical geometry: 16383,16,63
logical geometry: 89355,255,63 OR (???) 89355,16,63 ???
So what (which values) do I have to pass to the kernel?
???
Oh... and my BIOS is only capable in handling harddiscs <= 8,4 GB and
there is no further Bios-update available.
And the harddisc I spoke about is regocnized as a 8,4 GB harddisc with
255 heads and 1027 cylinders.
Should I let the BIOS detect the harddisc or should I enter "None" in
the BIOS-setup instead?
And should I pass "hdc=noprobe" to the kernel or not?
I am a bit confused about all this stuff with all these numbers...
Help on this would be great!
Kind regards
