I got a new reply about ICOP
We found the IDE driver in Real mode under Win98 can't distinguish our IDE Controller. So, under Device Manager, we will see both Primary & Secondary IDE Controller with an exclamation mark, that means we can only run in PIO mode, and it make system very slow. In Win98, even if the BIOS is changed to IDE Compatible Enabled, there is still an exclamation mark in Win98, and even if we try to change to the Intel IDE Vendor ID & Device ID, it does not work.
I have tried to modify it by following the link below, but I still can't get Win98 to drive our IDE Controller with the correct IDE Driver.
The reason why DOS is fast is that our BIOS has “PCI Bus Master Enabled” enabled, and DOS will run DMA Mode according to the BIOS plan.
I'm already sent this issue to our bios team, and keep you updated.
That's awesome that they are giving it some attention!! 😁
