W2K Server cannot Plug-n-Pray video

I have an Aopen MX36LE-UN motherboard that I have loaded W2K Server on. It refuses to recognize the onboard video controller and thereby attempts to use the 16 bit 800×600 settings, which will not do. I have downloaded their latest “4in1” program with drivers, but can’t seem to get it to recognize the drivers on bootup. This system previously had Win2K running on a desktop with no problems. I talked to the vendor and he used the same “4in1” drivers to load it up that I tried to use. This isthe first time I have tried to setup 2000 Server on such a board. Any ideas?
