The on-screen messages end with:
Code:
UDF-fs: No partition found (1)
XFS: bad magic number
XFS: SB validate failed
Kernel panic: VFS: Unable to mount root fs on ram0
But that was trying to boot the CD contents without unsquashing the rootfs. Is that barking up the wrong tree?
“
I'd probably unsquash the rootfs so that it can be mounted from just a normal ext2 filesystem (assuming that kernel can't do anything more modern).

Thanks. I added another hard drive and unsquashed that file onto it. I then copied the
Boot-NoEmul.img and
KnoppiXMAME (kernel) files to a new directory on that drive, and set up a new entry in GRUB.
But I just get an endless flickering screen of text and the keyboard stops working. I rebooted and tried to hit ScrollLock before that happened, which resulted in this message and the computer instantly freezing:
Code:
<0>Kernel panic: Attempted to kill init!
<1>Unable to handle kernel NULL pointer dereference at virtual address 00000000
printing eip:

*pde = 00000000

Would you normally use one kernel to load another ? I believe it can be done, but I'm not sure there'd be a huge benefit. You could just get the kernel sources and build it with the necessary drivers if you believe it is incomplete - it's not impossible that they skipped the hard disk drivers for a purely cd-based system. But if that's the case, the kernel for the hard-drive based knoppix could probably run your game system.

I wouldn't normally mess around with kernels at all! I'm a bit out of my league here, but always trying to learn something new.
I'm just running out of ideas as to how booting from HDD/USB might be possible. I didn't think it could be so hard!
Unfortunately I can't find a version of Knoppix
quite as old as KnoppiXMAME. I could download the subsequent version and give it a go... but I'm not really sure what I'd be doing when I got it...
Could I just copy the kernel and .img file to the KnoppiXMAME hard drive and boot with them...?
Or could I install the old Knoppix, manually overwrite the filesystem with KnoppixMAME files, then... er... I dunno.
Is it time to accept that booting this CD from hard drive just isn't possible?
