Hello!
I'm trying to set up Micropolis 3387WS SCSI-3 drive, and I'm totally lost.
How do I set up disk geometry? I'm attempting to set up 4811/21/168, which
is the values reported by kernel, and fdisk displays always NOT what I've
entered, but something weird.
(part of fdisk output)
******* Working on device /dev/sd4 *******
parameters extracted from in-core disklabel are:
cylinders=20228 heads=21 sectors/track=40 (840 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=20228 heads=21 sectors/track=40 (840 blks/cyl)
Do you want to change our idea of what BIOS thinks ? [n] y
Supply a decimal value for "BIOS's idea of #cylinders" [20228] 4811
Supply a decimal value for "BIOS's idea of #heads" [21] 21
Supply a decimal value for "BIOS's idea of #sectors" [40] 168
parameters extracted from in-core disklabel are:
cylinders=20228 heads=21 sectors/track=40 (840 blks/cyl)
Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=4811 heads=21 sectors/track=168 (3528 blks/cyl)
Are you happy with this choice [n] y
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 0, size 16992188 (8296 Meg), flag 0
beg: cyl 0/ sector 1/ head 1;
end: cyl 714/ sector 40/ head 20
Do you want to change it? [n] y
Supply a decimal value for "sysid" [0] 165
Supply a decimal value for "start" [0]
Supply a decimal value for "size" [0] 16992188
Explicitly specifiy beg/end address ? [n]
sysid 165,(FreeBSD/NetBSD/386BSD)
start 0, size 16992188 (8296 Meg), flag 0
beg: cyl 0/ sector 1/ head 0;
end: cyl 720/ sector 36/ head 7
Why 720/36/7? This wouldn't work!
And here is what sysinstall says:
WARNING: A geometry of 4811/21/168 for sd4 is incorrect. Using
a more likely geometry. If this geometry is incorrect or you...
... and so on. Than it insists on
DISK Geometry: 1057 cyls/255 heads/63 sectors, which doesn't work again.
What have I missed and where?

Novell worked on the same hardware ok :-(
