Hi Mark,

Thank you very much for your quick responses to my problem.

Due to your help I was now able to solve both problems.

Now everything works great (including UDMA and the ethernet NIC
and ACPI)
[however, the rtl8139 still refuses to work, but I can use the eepro100].

The three core things were:
- switch off apic stuff
- you may enable ACPI but you must _disable_ ide power down
in the BIOS (seems to be a bug somewhere)
- This message is normal and can be ignored:
PCI: No IRQ known for interrupt pin A of device 00:11.1. Please try using
pci=biosirq.

Regards,
Wolly
