Hi all-

I have been a knoppmyth user for about a year now and love it. I wanted to upgrade from R4v5 to R5a12, but have run into this error when I boot- "you have passed an undefined mode press to see modes or press enter to scan" I did some searching around and found that I should try noapic or vga=normal but no luck. So I entered one of the modes and it started to detect hardware. Ok I got passed that part, but then I get "mp-bios bug 8254" . I googled but could find no answers that seamed to make sense.

I am not able to run the latest knoppix on this box(same error), but both the Debian sarge installer and the R4v5 disks both work. I have even tried with it attached just to my tv and just to a monitor. The motherboard is a CHAINTECH "7NIF4" NVIDIA nForce2 IGP. Please help and thank you for your time.

That seems strange. I have the same board and R5a12 installed ok for me. At the boot: prompt I just pressed enter and it installed fine. What version is your bios? What other cards are installed in the system?

Thanks for the reply. The Bios is version 6.0pg the date is 07-19-2004. The cards in the box are a pvr 250 and a generic 5.1 sound card. This is the full message I am getting "mp-bios bug 8254 timer not connected to IO-APIC"

Thanks for the help...

You're installing while hooked up to a TV right? You also have the option to continue. Just continue... You will need to change vga=normal after installing (or you can wait an extra 30 sec each time you reboot).

Thanks for the suggestion Cesman, but I have tried that and have tried hooking it up to a monitor. I did somemore googling on the subject and have found it to be specific to NForce 2 motherboards. I am going to try to update the bios if there is one. The only thing I can think of ...

P.S. Cesman thanks for the time spent on this project.

I have an nforce 2 board and I see this when I installed with it hooked up to my TV. All I do is continue, you can also select a mode 25 row should do... It isn't a biggie and shouldn't prevent you from installing.

Cesman thanks for the advice and that does get me past the video mode problem, but I still get the "mp-bios bug 8254 timer not connected to IO-APIC" error. I think it has to do with a fault in the IO the way it is being read. I bought the Nforce2 board because at the time it was your reference board and the one Jared recomended. I am at a loss for what to do next. I dont mind staying with R4v5, but I do want the latest and greatest.

Thanks for your help and if anyone has had this problem let me know what you did to fix it.

you can also try looking in the bios for anything related to apic and turn it off, or try the noapic and or nolapic boot options.
