Hi,=20
I'm trying to install NetBSD 1.6.1 on x86.
When system boots from the CD, it seems
to recognize everything and detect my HD as=20
follow:
11474/5/312.

As the IBM disk (25L1910) doesnt have its specs=20
written on it,
i cant assume thats its 100% right. Anyway, it=20
finds the
good size (~8.7Go).

When i start the install, i have some error=20
message
about the disk geometry and i cant install the=20
base
system (not enought free space).

"sd0: mode sense (4) returned nonsense; using=20
fiction
fictitious geometry"=A0=A0

It seems that it uses a bad geometry=20
(1285327/64/32)=20
and finds a negative size (-811824.92Mb).

I also tryed to fix it with this command (first=20
using netbsd spec,
11474/5/312 and several others tests...):

fdisk -f -i -b ${DLCYL}/${DLHEAD}/${DLSEC} ${disk}

Then i have the above message "mode sense [...]",
and this one:

"Invalid fdisk partition table found"

Using the tekram's SCSI bios, i did a low format=20
on the
drive... without any success.=20
Any help or ideas would be really appreciated.

thomas.

PS: NetBSD 1.6.0 and 1.6.1 are running fine on the=20
same
box with an IDE drive.
