Cannot switch distro in GRUB after reboot (Tripe-Boot-Setup)

[tommac_osx86]

I cannot select my distro within GRUB after rebooting from OSX86 10.5.6 (iPC); keyboard inputs are ignored; if I reboot from XP or Ubuntu (or just press my reset button once again), there is no problem. I have three primary partititions.

 

How to solve this problem?

If you're saying that keyboard inputs are being ignored by GRUB after a reboot, then it sounds like the OSx86 keyboard driver is messing up something about the way the keyboard hardware is configured. I have two suggestions:

 

• As a workaround, try pressing the Reset button on your computer (iif it's got one; some cheap ones don't) after the system has completely shut down and begun its reboot. Any time after the BIOS screen first appears should be fine. This may reset the hardware to whatever state the BIOS expects.
  
• As a better solution, you could try experimenting with settings relating to the keyboard in your BIOS. The exact options that are available vary from one BIOS to another, so I can't be more precise. Relevant options might also depend on whether you've got a PS/2 or a USB keyboard. For instance, some BIOSes have options that effectively make USB keyboards look like PS/2 keyboards for very old OSes, such as DOS. I wouldn't expect this option to have any effect on PS/2 keyboards -- but then again, weirder things have happened.

I think so, too...is there anything to configure in OSX86 directly or a kext I could apply?

I know, it works with the reset button, but it's a bit annoying

I have a USB keyboard plugged to a USB-Port (not via PS2-Adapter!). Does any one have a working BIOS setup for my GA P35-DS3 Mainboard?

Hmmm, I will give it a try...
