How are you? 
I have run into some question running FreeBSD.

I am running FreeBSD 4.1.1 on a Tyan board what has ServerWorks ServerSet III HE-SL chipset.
I am not sure if FreeBSD 4.1.1 recognize ServerSet III HE-SL chipset.
Followings are the messages regarding PCI bud on the boot up.

<----------------------------------------------->
pcib0 : <RCC host to PCI bridge> on motherboard.
pci0 : <PCI bus> on pcib0
pcib4 : <PCI to PCI bridge (vendor=1166, device=0009)> at device 0.1 on pci0
pci1 : <PCI bus> on pcib4
pci1 : <S3 Trio3D/2X graphics accelarator> at 0.0
pci0 : <unknown card> <vendor=0x1274, dev=0x1371) at 2.0 irq 2 
isab0 : <PCI to ISA bridge (vendor=1166, device=0200)> at device 15.0 on pci0
isa0 : <ISA bus> on isab0
.

pcib1 : <RCC LE host to PCI bridge> on motherboard
pci2 : <PCI bus> on pcib1
tio0 : <3Com 3c985-SX Gigabit Ethernet> mem 0xfebfc00-0xfebfffff irq 9 at device 2.0 on pci2
tio0 : Ethernet address : 00:60:08:a1:e4
pcib2 : <RCC host to PCI bridge> on motherboard
pci3 : <PCI bus> on pcib2
pcib3 : <RCC host to PCI bridge> on motherboard
pci4 : <PCI bus> on pcib3
<------------------------------------------------>

ServerSet III HE-SL use following 3 chips.
NB6576 : north bridge
SB7440 : south bridge
NB6555 : PCI bus bridge 

As you can see from above messages, ServerWorks chips are correctly detected. (vendor=1166)
However, only 2 chips are detected.  In addition, pcib1 is <RCC LE host to PCI bridge>.
I suspect that FreeBSD detects HE-SL chipset as LE chipset that uses only 2 chips (NB6635 and IB6566).

Does FreeBSD 4.1.1 detects ServerWorks III HE-SL chipset?
If FreeBSD does not confuse HE-SL with LE, does FreeBSD really utilize full capacity of HE-SL chipset?
 
Please help me with this.
Any information will be greatly appreciated.

Thanks in advance.
