The problem is, that booting takes about 15 minutes, it hangs up with the message "Disabling IRQ #15".
Most of the times, IRQ #15 is for the IDE Controller.
There may be some helpful informations in the following files at boot time. I have put some content of mine under these files:
/proc/interrupts
15: 1300000 XT-PIC ide1
/var/log/messages
Disabling IRQ #15
hdc: lost interrupt
irq 15: nobody cared!
/var/log/dmesg
Disabling IRQ #15
ide-cd: cmd 0x3 timed out
hdc: lost interrupt
irq 15: nobody cared!
Unfortunately, the BIOS of my Acer TravelMate 513TE (510 Series) had no IDE configuration parameters. I was not able to go around this problem. No Mandriva Linux on my machine... :(
