Hi everybody,

Recently I installed the SCO OpenServer 5.0.4 on a second disk drive
(don't ask me why). To minimize the pain of using this "user-friendly"
OS I tried to mount it's partition from Linux, but it doesn't seem to
work. I cannot do it neither in 2.0.29/30 nor in 2.0.32.

Here is the situation. Unlike Linux, SCO runs from primary disk only,
so I basically moved my Linux disk to a secondary IDE controller (hdc)
and yanked in another one for SCO (as a primary one) (hda). This disk
is fully devoted to SCO. Here is the divvy output:

==================================================================
# divvy

/stand on /dev/boot read only on Wed Dec 03 21:15:16 1997
==================================================================

Linux, in turn, sees the following picture:

==================================================================
ide: i82371 PIIX (Triton) on PCI bus 0 function 57
ide0: BM-DMA at 0xe800-0xe807
ide1: BM-DMA at 0xe808-0xe80f
hda: DSAA-3540, 504MB w/96kB Cache, CHS=512/32/63
hdb: TOSHIBA CD-ROM XM-6002B, ATAPI CDROM drive
hdc: IBM-DAQA-32160, 2067MB w/96kB Cache, CHS=4200/16/63, DMA
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
ide1 at 0x170-0x177,0x376 on irq 15
Floppy drive(s): fd0 is 1.44M
FDC 0 is a post-1991 82077
Partition check:
hda: hda4
hdc: [PTBL] [525/128/63] hdc1 hdc2 hdc3
==================================================================

Linux fdisk reports the following partition info on hda:

==================================================================
# /sbin/fdisk /dev/hda

Command (m for help): p

Disk /dev/hda: 32 heads, 63 sectors, 512 cylinders
Units = cylinders of 2016 * 512 bytes

Device Boot Begin Start End Blocks Id System
/dev/hda4 * 1 1 511 515056+ 63 GNU HURD

Command (m for help): q
#
==================================================================

So, this is the setup. Now I'm trying to mount /dev/hda4 as a sysv
filesystem:

==================================================================
# mount -t sysv /dev/hda4 /mnt/sco/
VFS: unable to read Xenix/SystemV/Coherent superblock on device 03:04
mount: wrong fs type, bad option, bad superblock on /dev/hda4,
or too many mounted file systems

# mount -t sysv /dev/hda /mnt/sco/
VFS: unable to read Xenix/SystemV/Coherent superblock on device 03:00
mount: wrong fs type, bad option, bad superblock on /dev/hda,
or too many mounted file systems
==================================================================

Needless to say, the sysv filesystem is compiled in the kernel (as a
module). I even try to compile it in not as a module - no change.

Thanks in advance,

Finally, here is an output of my sysinfo script, used to print the
basic Linux and hardware configuration:
