K6-2 450, 256mb ram, 20gb ide fujitsu hard disk. Every time I boot up I get this unsettling message about PCI: No IRQ known for interrupt pin A of device 00:0f.0. Please try using pci=biosirq. It turns out that 00:0f.0 is my ALi ide controller: 00:0f.0 IDE interface: Acer Laboratories Inc. [ALi] M5229 IDE (rev c1) Is this normal, or what should I do to "fix" it? Changing plug and play OS in the bios has no effect. dmesg and lspci follow: Linux version 2.4.3 (root@coffee) (gcc version 2.95.3 20010315 (release)) #2 Sat Mar 31 17:50:50 PST 2001 BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000000fffc000 (usable) BIOS-e820: 000000000fffc000 - 000000000ffff000 (ACPI data) BIOS-e820: 000000000ffff000 - 0000000010000000 (ACPI NVS) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) On node 0 totalpages: 65532 zone(0): 4096 pages. zone(1): 61436 pages. zone(2): 0 pages.
