>Description:
Now, ALTIMA AC1001 base NICs are out of suport list.
I tried AC1001 base giga NIC and it worked.
AC1001 is almost comptible with AC1000, so i tried to add device id to current bge driver.
But, it can work with very short packet only, like ping, on my A7M266-D(AMD762 chipset) base box. and the other packets timeouted.
I additionaly tried little PCI cache line size(1) and got a good result.
I tested these using KUROUTO SHIKOU AC1001GB-PCI64 (CAMEO's OEM product).
