Hi all,

I managed to compile seabios on 32 bit host. I tested it on following hw:

Asus M2V-MX SE (K8M890/VT8237S) + coreboot

Bus 005 Device 002: ID 1e3d:6025
Bus 002 Device 004: ID 04f2:0116 Chicony Electronics Co., Ltd KU-2971 German
Keyboard
Bus 002 Device 005: ID 0430:0005 Sun Microsystems, Inc. Type 6 Keyboard

It has UHCI and EHCI the USB stick was EHCI connected.

In summary, USB keyboard works! Both of them, autorepeat is working too. The
only minor thing I could not use them BOTH connected ;)

USB booting works too! I booted from USB stick the FreeDOS, USB keyboard still
worked :) !!!

And to make it even more fancy, I used the vgabios.bin from the SeaBIOS.
(marked in CBFS as pci1106,3230.rom)

Because Luc did the VGA init in the Coreboot of the Chrome9 VGA, the legacy VGA
does work with legacy SeaBIOS option rom ;)

There is some glitch that part of the image contain old data during some editing
experiments in grub, but maybe just page switching is not correct? Dont know.
But it was usable :)

Rudolf
