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 */

lies (bus) */

d give 0 after the sum of all bytes for this structure

(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:
