Hi,
thank you for your response. I have read about the looping problem that this
could be caused by some IRQ/DMA problem. Here is the output from /rpoc:
cat /proc/interrupts
CPU0
0: 99385 XT-PIC timer
1: 6 XT-PIC keyboard
2: 0 XT-PIC cascade
8: 2 XT-PIC rtc
9: 0 XT-PIC VIA686A
10: 4555 XT-PIC eth0, usb-uhci, usb-uhci
12: 6 XT-PIC PS/2 Mouse
14: 11260 XT-PIC ide0
15: 9 XT-PIC ide1
NMI: 0
ERR: 0
the problem with the bios is, that with this brand new HP notebook, one
cannot do any changes to the bios. The bios setup program lets one set the
date and booting device and that's it!
There must be a way around this, but I don't know how at the moment.
So I don't know whether there is the option PnP Bios installed.
Speaking of interrupts, how does one change those if not in the bios?
Thanks for your help,
Hauke
