Actually the irqtable entries is only for peer root pci bus scan when
mptable is used.

So you need to make sure mptable is right, and put entries for
hypertransport chain other than on bus0.

Dear YH,

excuse me, how about the irq_tables.c?

should I modify it like tyan/s2882 did.

printk_debug("setting Onboard Broadcom NIC\n");
        static const unsigned char slotIrqs_8131_1_9[4] = { 5, 9, 0, 0
};
        pci_assign_irqs(bus_8131_1, 9, slotIrqs_8131_1_9);
        write_pirq_info(pirq_info, bus_8131_1,(9<<3)|0, 0x1, 0xdef8,
0x2, 0xdef8, 0, 0, 0, 0, 0, 0); 
        pirq_info++; slot_num++;

2006/6/20, Lu, Yinghai :

You need to update the entries at mptable.c for your slots or onboard
pci device.

Dear YH,

got it.

Thanks for the information and your help.

[LinuxBIOS] New guy in LinuxBios

[Vincente Tsou]

Hi YH,

Thanks again for your help.

Now I can active all devices in my LinuxBios, it almost done except VGA
function.

I appended a 36k VGA option rom to LinuxBios, and enable Options about VGA.

And I got the halt_sys message:

PCI: 04:02.0 init
rom address for PCI: 04:02.0 = fff80000
copying VGA ROM Image from 0xfff80000 to 0xc0000, 0x9000 bytes
entering emulator
halt_sys: file
/home/vincente/LinuxBIOS/LinuxBIOSv2/src/devices/emulator/x86emu/ops.c, line
4387
PCI: 01:04.0 init

then, I can see something output, but the output is like snow screen and I
can't read anything.
I think it is working in the wrong mode.

When I made a blind type 'root' and password, I can login the Linux, and
then the screen became clear. (work fine)

I wonder how to fix the problem? is the halt_sys message normal ?

I also got another question, could it possible boot to MS-DOS floppy/USB
disk.
The MS-DOS needs a lot INT function in BIOS, does LinuxBios able to support
it?

[LinuxBIOS] New guy in LinuxBios

[yhlu]

the snow screen only happened when I was debugging the onboard VGA support.
So i move the CPU init before other pci device init call. That is
something related to mtrr setting around [0xa0000-0xb0000) the font
buffer.
the halt_sys display is normal...it means the vga option rom is
executed successfully.
you can use filo in etherboot to boot from usb stick.

Hi,

Excuse me....

I don't know how to move the CPU init before other pci device init call....
sorry.

I have tried to find it, but .... :(

Other question: How did you produce your vga bios image? you should
extract it from the vendor bios image, not from memory, as some modify
themselfes.

And, no, sorry, booting MSDOS is not possible at the moment (except
maybe with ADLO, which has not been developed in a long time)

Hello Stefan,

Yeah, the VGA BIOS is extract from vendor bios image.

Thanks for your update of MS-DOS.
