RE: [LinuxBIOS] PCI information changed when linuxbios is used

[Lu, Yinghai]

It's more logically right to put SB HT chain in bus1. because it is
under HT host bridge. (0:0x18.0).

Anyway it is doable to put SB chain on bus 0 in LinuxBIOS, you may need
to modify amdk8_scan_bridge, 
1. process SB link at first. 
2. not use max instead of ++max for sb link.

Also AMI 8111 start from 0:6.0 and 8131 from 0:a.0
And PH 8111 start from 0:6.0 and 8131 drom 0:1.0

Subject: [LinuxBIOS] PCI information changed when linuxbios is used

Dear all,

I made an Iwill/DK8S2 machine run on LinuxBIOS. But I
noticed that pci information shown by lspci changed a
lot. Is this normal?

Here i post the pci information before and after
linuxbios is used.

when factory-build bios is used, the results of lspci
are:

> From the above, IDE interface, ethernet intefrace and

usb interface belongs to different buses before and
after using linuxbios. This is surprising. Could
someone provide some advices?

Thanks.
