booting without VGA
Hi!
I'm currently wokring on a embedded system for a camera device. It runs linux and we use the M-Systems DiskOnChip driver (a seperate module available from their site) for storage and as a boot device.
The problem is if we boot with a kernel WITH vga support enabled, it boots fine. If we disable vga support it doesn't seem to boot. What makes it even stranger is that if we boot with that same non-vga kernel using an IDE disk as boot device it also boots fine.
Solving the problem is probably trivial, but I have no way of debugging/finding out the problem since I can't see the error message or at what point the kernel stops working.
Remember it doesn't get to the point where syslogd could start, so I can't save the bootup messages to disk or anything.
Also if I enable vga support the error disappears, so I'm sitting with a catch-22 situation.
Any ideas how I can found out/debug the cause of the problem?
PS: Could you please post answers to me personally, I'm not subscribed to the mailinglist

Please ask M-Systems to debug your problem. We don't have source code to their driver so we cannot help you.

You're using binary-only code. You shouldn't expect anyone on the l-k mailing list to give your problem a second thought.
Does it work if you use the GPL'd DiskOnChip driver which is in 2.4.0-test12? You can also use it in 2.2 kernels.
