Making bootable hp300 CD

[Mike Nicewonger <twmaster@twmaster.com>]

Hi all,

I am trying to make a bootable hp300 installation CD. I see where the official
distro CD is bootable and am trying to figure out how to replicate that. I have
tried to make some cd's using mkisofs and have just managed to create coasters.
I know the sys_cdboot file needs to be present but what else am I missing?

I have tried to make 9660 and 9660 rockridge disks. I have hit the brick wall.

TIA
