/dev/hda boot

Hi

I've created a live cd with bootcd (great package!) which works fine on 
qemu and on my pc (both by choosing hdc as the boot option).

However, the target system I need to use it on has the cdrom on 
/dev/hda. But when I pick hda it says "not found". I've checked my 
bootcdwrite.conf and the CDDEV line is

CDDEV="/dev/hda /dev/hdb /dev/hdc /dev/hdd /dev/scd0 /dev/scd1"

I can't use auto because I've got no initrd - I understand I need an 
initial rd to use auto?

And one more problem - X won't start because it says 'device not found'. 
The image was built within a Qemu session which I think emulates a 
Cirrus Logic card. Is it simply a matter of me installing drivers for 
the target system on the Qemu session before I create the iso?

Thanks for any help you guys can give!
