This mornings tech fax states, Asus has shipped countless motherboards with bug in PCI slots.
Thousands of motherboards for Intel and AMD have shipped with known problems. PCI slots do not PNP sound cards, video cards, game devices, and misc other cards properly.
All AMD based motherboards built after Jan 9, 2001
all P4T, P4T-m, CUSL2-c
New BIOS will be posted later this month.
Solution, go into your device manager and delete the problemed device, reboot and enter bios. turn PNP off and restart. re-setup device. If this does not fix it, move the PCI card to slot 4 and try again. PCI slot 1/5 are shared IRQ and 2,3,4 are autoassigned upon card insertion with PNP on.
Most commonly effected cards are sound cards, and the joystick/midi port. This list was too long to retype, so I will name a few cards that are common by chipset.
SB (all models), MX80~400, ESS, Aureal V1 and V2, and anything with those chips onboard.
Cards with "Mutltifunction parent", Cards with bios onboard (nic, PCI video,...)
RMA's will not be issued, this problem wil be fixed with bios update.
I have a problem like that, Windows keeps on detecting "Unknown PCI Storage Controller", when all I have is my sound card and 10.100 ehternet card. Probably has nothing to do with this problem, though.....
I work with P3's and P4's at work, and when we do the W2K installs, they always come up with an unknown PCI device. After lots of researching and talks with Gateway (whom we buy the PC's from), the PCI device turns out to be the chipset controller!
We have to manually install it from the Gateway support CD (it has its own separate setup file, that's why windows driver update won't find it).
According to the readme, it's supposed to be for the following chipsets:
Intel(R) 810 Chipset
Intel(R) 810E Chipset
Intel(R) 815 Chipset
Intel(R) 815E Chipset
Intel(R) 815EM Chipset
Intel(R) 820 Chipset
Intel(R) 820E Chipset
Intel(R) 840 Chipset
Intel(R) 430TX PCIset
Intel(R) 440BX AGPset
Intel(R) 440DX AGPset
Intel(R) 440EX AGPset
Intel(R) 440GX AGPset
Intel(R) 440LX AGPset
Intel(R) 440MX Chipset
Intel(R) 440ZX AGPset
Intel(R) 850 Chipset
and supposed to provide proper support for AGP, USB, ISAPNP, and ATA 33/66.
