Dear lists, I have two questions: (1) I use getpir(8.30 freebios v1) to get irq_tables.c of epia-500. I have compared mine with one under mainboard/via/epia. They are always different. What cause it? My irq_tables.c is as following: /* This file was generated by getpir.c, do not modify! (but if you do, please run checkpir on it to verify) Contains the IRQ Routing Table dumped directly from your memory , wich BIOS s ets up
Documentation at : http://www.microsoft.com/hwdev/busbios/PCIIRQ.HTM */
#include <arch/pirq_routing.h>
const struct irq_routing_table intel_irq_routing_table = { PIRQ_SIGNATURE, /* u32 signature */ PIRQ_VERSION, /* u16 version */ 32+16*5, /* there can be total 5 devices on the bus */ 0, /* Where the interrupt router lies (bus) */ 0, /* Where the interrupt router lies (dev) */ 0x1c00, /* IRQs devoted exclusively to PCI usage */ 0, /* Vendor */ 0, /* Device */ 0, /* Crap (miniport) */ { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }, /* u8 rfu[11] */ 0x88, /* u8 checksum , this hase to set to some value that woul d give 0 after the sum of all bytes for this structure (including checksum) */ { {0,0x98, {{0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xd eb8}}, 0x2, 0}, {0,0x50, {{0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xd eb8}}, 0x3, 0}, {0,0x58, {{0x4, 0xdeb8}, {0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xd eb8}}, 0x4, 0}, {0,0x8, {{0x1, 0xdeb8}, {0x2, 0xdeb8}, {0x3, 0xdeb8}, {0x4, 0xde b8}}, 0, 0}, {0x50,0, {{0, 0}, {0, 0}, {0, 0}, {0, 0}}, 0, 0}, } };
(2) I've got QDIA6T MB based on vt8601 and vt82c686. I have made some progress on this MB(8.30 freebios v1). The romimage can find VGABIOS, but unsupport int error occurred. The output log is as following:

I don't know about your pir difference problems but your irq_tables and the "unsupported int" messages in the vga translation code are not really related to each other.
The unsupported int is telling you that the vga bios made a int call that is not suppoted by linuxbios. These are software interrupts and only remotly related to irqs which are hardware interrupts.

that's why irq_tables.c is different.
you need to look up what those unsupported int's are and see if they are real or an error or some sort.
