[syslinux] ISOLINUX: Boot problems

I'm trying to setup a Linux CD on mashine that will have nothing but a
CDROM. Everything worked fine until I removed the HDD. From this moment on
the CD doesn;t boot. I upgraded to Syslinux 2.0 but with no luck. The error
message I got almost says it all: "Extremely broken BIOS", but can I ask for
help if there some ideas how to fix this, cause if I put the HDD back the CD
boots without any problem.

The hardware:
CPU: VIA C3 Samuel2 1Giga Pro

lspci output:
00:00.0 Host bridge: VIA Technologies, Inc. VT8601 [Apollo ProMedia] (rev
00:01.0 PCI bridge: VIA Technologies, Inc. VT8601 [Apollo ProMedia AGP]

01:00.0 VGA compatible controller: Trident Microsystems CyberBlade/i1 (rev

The CD is primary slave (and there is no way to put it as a master) and
there is a some HDD as a master. If both are available boot CD is working
OK, if I disable HDD from BIOS (or remove it) the CD doesn't boot.

I burn one CD with isolinux.bin-debug and here is its output:
isolinux: Starting up, DL = 9F
isolinux: Loading spec, packet failed, trying to wing it
isolinux: Extremely broken BIOS detected, last ditch attempt with drive = 9F
isolinux: Loading main image from LBA = 00031A21
isolinux: Sectors to load = 0004
isolinux: Disk error 01, AX = 4221, Drive 9F

So any info would be appreciated, even one thats says that its BIOS fault.
