I just found out some differences in lspci -vvv between original BIOS flash
and Linuxbios:
1) Why when booting with Linuxbios, the IDE interface uses pin A, and why it
is routed to IRQ = 0? Shouldn't it be irq=14 for IDE?
With Linuxbios:
00:00.1 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] (rev d0)
(prog-if 80 [Master])
Subsystem: Unknown device ab34:12e6
Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B-
Status: Cap- 66Mhz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
Latency: 16
Interrupt: pin A routed to IRQ 0
Region 4: I/O ports at 2040 [size=16]
With std BIOS flash:
00:00.1 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] (rev d0)
(prog-if 80 [Master])
Subsystem: Elitegroup Computer Systems: Unknown device 0a01
Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-

<TAbort- <MAbort- >SERR- <PERR-
Latency: 16
Region 4: I/O ports at 4000 [size=16]
2) Why with Linuxbios modem doesn't gets the latency?
With linuxbios:
00:01.6 Modem: Silicon Integrated Systems [SiS]: Unknown device 7013 (rev
a0) (prog-if 00 [Generic])

With standard BIOS:

I have tryed pci_config_write_byte(device,PCI_LATENCY_TIMER,32) , it didn't
work.....
