Title: Epox 7KXA, Win2K & AGP:
I can't seem to get 4x and SBA enabled for my Geforce video card. The problem
appears to be Win2k not recognizing the Northbridge (i.e. there are no AGP
devices under Device Manager). I did do a clean install and I'm running the
latest Nvidia reference driver (3.78). Anyone have any ideas?
I had posted a similar message on the Epox News group and received zero
responses to either posting. Since no one offered any solutions I started
digging for answers. I compared data sheets from various VIA chipsets to the
Win2K INF that provides PNP support for chipsets. I found that the device ID
have changed with the 8371 Northbridge even though functional the Northbridge is
very similar to previous VIA chipsets. Anyway to make a long story short I was
able to get the chips set properly detected and AGP mode and 4X mode enabled.
SBA is still alluding me.
The Fix:
added the following 4 lines to C:=WINNT\INF\machine.inf
Under [VIA_SYS] section %PCI\VEN_1106&DEV_0391.DeviceDesc% = NO_DRV, PCI\VEN_1106&DEV_0391
%PCI\VEN_1106&DEV_8391.DeviceDesc% = VIAAGP_Install,PCI\VEN_1106&DEV_8391
Under VIA_MFG = "VIA" section
PCI\VEN_1106&DEV_0391.DeviceDesc = "VIA Tech CPU to PCI bridge"
PCI\VEN_1106&DEV_8391.DeviceDesc = "VIA Tech CPU to AGP
Controller"
I then went into Device Manager and removed the following device from
"System Devices":
Standard PCI to PCI Bridge
After that, reboot and Win2k will redetect and properly install support for the
KX133 chipset. I've also attached the complete modified machine.inf.
