新bios V1.1修正

CD 6.35VI 驱动只支持 4 种类型. 他们是 P4IBAS,P4IBMS,P4IBAS2,P4ITA2.

我们发现那是因为 ID 不同. CE 版本Offset 8 是30H, CD 版本 offset 8 是 10H.因此它受到了限制.

P4VXAS和P4VXASD可以支持SDRAM，但是不支持DDR RAM，因为硬件仅实现支持ECC的SDRAM.

No, the P4VXAS V1.1 comes with VIA 8233 chip which supports USB 1.1 only.

Yes, the P4VXAS V1.1 supports hard drive capacity up to 160GB.

No, the P4VXAS V1.1 supports AGP mode up to 4X (1.5V only). You can install an AGP 8X card on this MB but the card will run with AGP 4X mode.
