My buddy at work suggested very interesting idea. If you look carefully at the
GC-SL chipset web page, it claims it uses CSB6, not CSB5.
CSB5
* PCI 2.2 32bit/33MHz
* Legacy functions (8237DMA, 8259PIC, 8254Timer)
* PCI to LPC bridge
* XIO-APIC for multiprocessor systems
* 4 Port USB 1.0 interface
* ACPI power management and event detection support
* Dual Channel ATA-100 hard disk controller
CSB6
* PCI 2.2 64-bit/33MHz
* Legacy functions (8237DMA, 8259PIC, 8254Timer)
* PCI to LPC bridge
* XIO-APIC for multiprocessor systems
* 4 Port USB 1.1 interface
* ACPI power management and event detection support
* Three ATA channels supporting up to 6 hard disk drives
* Server Appliance functions: Watchdog timer, NVRAM support, LCD and
Keypad support
However, diagram still shows it uses CSB5. :-( His point was one of us may
have CSB6, not CSB5, although there's no difference in device ID and revision
numbers.
Here is P4DSE's pciconf:

This is Dell's pciconf:

ohci0@pci0:15:2: class=0x0c0310 card=0x02201166 chip=0x02201166 rev=0x05

isab0@pci0:15:3: class=0x060100 card=0x02301166 chip=0x02251166 rev=0x00
hdr=0x00
The only difference I can see is the functions of 0x02011166 and 0x02251166
are switched. Somebody did very screw-up job. ServerWorks? SuperMicro? Dell?
I don't know.
