[LinuxBIOS] LinuxBios FILO VxWorks

[Edik Fainshtein]

Hello everybody,

My problem is simple to describe. I am trying to boot VxWorks from LinuxBios.
I use compact flash on which I put my "bootrom" and my "VxWorks". I use iWill
DK8-HTX.

I have a success to boot the "bootrom" or the "VxWorks" immediately after FILO.
However, after booting my "bootrom" I cannot boot VxWorks image from the
"bootrom" on the same flash. I do have success booting VxWorks from a flash
connected to another IDE controller.

Original AMIBIOS (instead of LinuxBIOS + FILO) works fine in the same situation.
It seams like FILO makes some IDE initializations which VxWorks doesn't 
understand.

Any ideas?

Thanks

As I remember: The bootrom is a shrinked VxWorks that's responsible to load 
the final VxWorks from any source (including network, IDE etc.). It contains 
a 16 bit part to be loaded by the BIOS. The final VxWorks is 32 bit only.

"bootrom" is a VxWorks bootloader in ELF format. Actually, I can load
VxWorks image directly from FILO.

I found a solution to my problem. FILO disables IDE interrupts, so I just
right 0x80 to control IDE register (ports 0x3f6 or 0x376).
So, it works.
