Hi guys,
Recently, I find my ATI 7500 video card not work well under WIN3.11(DOS 7.1) with two ISA sound cards, SB AWE64 and ALS007.
When I enter into Win3.11, the start-up sound will hang, and I've tried to disable the start-up sound, but it is no use. When I play back some WAV /MID files, the sound will still hang, and so I have to reset my PC. In the BIOS, the PnP/DMA has been already set to legacy ISA.
But when I change 7500 to MX440 or FX5500, it works well. It is so strange! Does anyone know the detail reason?
I recall seeing an article that says there is a BIOS ROM on the nvidia cards whose address starts from C000:0000, but on ATI card I have no mind.
Thanks in advance.
