grub and gate A20 on legacy free boards (here: without keyboard controller)

[Gerd Koenig]

Hello,

I've already read some issues about grub having problems to boot when there's 
no keyboard controller on it. But I didn't find any solution yet, so can 
anyone point me to a solution or a workaround?

I'm currently developing on an ATCA Processor module (AMC) based on pentium 4, 
which will not have any keyboard controller onboard. Using Grub as the 
bootloader will fail, as it hangs in an endless loop in the GateA20 routines.

One workaround until now was to use LILO bootloader instead. But Grub should 
be the prefered bootloader, also, because it's the only one "really" 
supported by RedHat Enterprise Server WS 4.

Any help to solve this problem would be very appreciated.
Thanks in advance!
