Hi,
I get the following message at boot:

Then, at IDE init:

Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
VP_IDE: IDE controller at PCI slot 00:11.1

Rebooting using pci=biosirq as requested:

lspci -vvv shows this:

"pin A routed to IRQ 0" seems a bit strange... but everything is
working. Btw, I've been running 2.4.41 with ACPI and it's rock solid.
This is the log:

Another strangeness: when I reboot the machine (shutdown -r) my HD is
powered off: I can hear it spinning down when the screen goes blank and
spinning up when BIOS probes IDE channels.

The motherboard is an Epox8K3A (via kt333) with the latest bios.
