Bios Bug help required please!

Hi.

This is my first post and I'll jump right in with a question!

I installed the Ubunti 9.04 (64 bit version) and found that on boot up I got the following error message:

"0.348000 MS Bios bug....8254 timer not connected to IO-APIC"

After this it boots (I hear the boot up music) and end up with a blank screen. Every time. The only option is to crash the system.

So although my Acer has a 64 bit processor I then tried installing the 32 bit version. Same error message as before except it will boot and run normally. Quiet well in fact. Once in a blue moon I do get a blank screen but its very rare. The only thing that doesn't work is I cant seem to set the system clock and have to do it in the bios setup.

I also get this error msg if I boot from the live CD.

I have tried flashing the bios with an update but no difference.

From what I read this problem usually occurs when one a newer motherboard with an older OS not the other way round as in my case.

Any suggestions or perspectives on this problem?

Mike
