undionly hangs at initialising devices

[mimiko]

Hello.

There is a problem on an Asus P7H55D-M PRO motherboard. I've compiled undionly.kpxe with an embedded script. undionly.kpxe works on teste different computers and in vbox.

On this motherboard undionly.kpxe stucks at "iPXE initialising devices...".
I've added DEBUG=undionly:3,undinet:3,pxeparent:3
On normal computers I see some text in red. On this motherboard the result on screen is:

PXE->EB: !PXE at 9A78:0070, entry point at 9A78:0109
UNDI code segment 9A78:2cE4, data segment 906B:A0D0 (577-630kB)
UNDI device is PCI 02:00.0, type DIX+802.3
577kB free base memory after PXE unload
iPXE initialising devices... UNDINIC 0x2645cusing UNDI 0x891c5438

At at this point computer is hanged. Using stock undionly.kpxe behaves the same (only debug info is not printed).

Hope to resolve the problem.
