Problem with setup_harddisks

[Axel Freyn]

Hello,

we have a problem with setup_harddisks on some special machines:
We are using FAI 3.2.4 and Debian etch.

We have some dual-boot clients with Win98 and Linux. In order to get Win98
in a "save" state, we special PCI-cards which control the accesses on the
harddiscs from Win98. Re-installing Win on these machines is awful, so we
would like to preserve the partition-table with 2 primary and 3 logical
partitions. Because of these special PCI-cards, we HAVE to:
 - use exactly 2 primary partitions
 - install grub into /dev/hda1, NOT the mbr
 - mark the first partition as bootable

As disk-config, we are using:
disk_config disk1
primary  /boot/         10-100                  ; boot
primary  -              preserve2
logical /               9000-14000      rw,errors=remount-ro ;  -j ext3
logical swap            400-600         rw
logical -               preserve7

>From that, the following partition.hda - file is created:

unit: sectors

/dev/hda1 : start=        63, size=     79569, Id= 83, bootable
/dev/hda2 : start=     80325, size=  20482875, Id=  c
/dev/hda3 : start=  20563200, size=  57560895, Id=  5
/dev/hda4 : start=         0, size=         0, Id=  0
/dev/hda5 : start=  20563263, size=  20635713, Id= 83
/dev/hda6 : start=  41199039, size=    907137, Id= 82
/dev/hda7 : start=  42106428, size=  36017667, Id=  c

which looks quite reasonable - except may bo for the partition /dev/hda4?


But setup_harddisks seems to have a problem with that:

Creating partition table: LC_ALL=C sfdisk -q  /dev/hda <
/tmp/fai/partition.hda
Warning: The partition table looks like it was made
  for C/H/S=*/255/63 (instead of 77504/16/63).
For this listing I'll assume that geometry.

sfdisk: bad input

Does someone know a solution? Of course, one possibility would be not do
partition the disk at all - as everything is already correct now. How could
we achieve this? and what is the structure for /tmp/fai/disk_var.sh - I
expect, this file would have to be created by a hand-written script?
