My MB is modern (PIII 450MHz - GigaByte Intel 440BX of
one and a half year ago).
The disk works fine on many linuxes (Mandrake 8.1, Red
Hat 7.3 and Debian 2.2r5) and on Windows 2000 on the
same system.
Another 10GB Maxtor disk with 19841 cylinders has the
core FreeBSD system on it and it works well.
The problem relies into the BSD label for the main
disk (i.e. /dev/ad2)
I've edited this label from linux fdisk and set it up
correctly.
Then I reboot FreeBSD and the command disklabel
/dev/ad2 shows 4092 cylinders instead if 39693.
If I execute disklabel -r /dev/ad2 the cylinder count
is ok, meaning the disk copy of the label is correct.
The kernel in-core BSD label is always incorrect and,
as FreeBSD fdisk relies on it I can't create a
partition greather tha 2 GB (4092 cylinders)
Worse, if I set up the partition from linux fdisk and
the correct BSD label, when I boot FreeBSD the in-core
BSD label is still 4092 cylinders and the ata driver
complaints about having a partition too big.
If try to edit the BSD label the ata driver block the
writes.
I don't understand why from BSD there's no way to
force a new BSD label.
