Decrease the ISA bus speed, second screenshot. Right now the ISA is working at 16.5MHz, 66/4=16.5.

ISA Bus Clock Option : PCICLKI/6

Also increase the keyboard controller clock.

Copy code to clipboard

1Keyboard Controller Clock : 16Mhz

Are you sure about that?
Internal clock = 66MHz on this board? Really?
Then the correct setting for ISA would be /8

On a DX/2 the bus would be running at 33.3 MHz and so also the PCI bus. /4 is a normal divider for a 33 MHz bus and would result in 8.33 MHz ISA bus.

So I should leave PCICLKI/4?

I think so, yes.
What is also wrong then is the ratio Host clock / PCI clock. It is now 1: 1/2 according to your screenshot.
That would mean PCI bus is running out of specification (16MHz), it is below the allowed minimum, which is 25MHz as far as I know.
So => 1:1 then it should be 33MHz. graphics should be again faster.

Now when I think about it, when your PCI clock is now 16MHz, then the ISA clock would be only 4 MHz now? Weird.

Nowe Set 1:1, somehow bios changed it. Sound issue still in Doom like.

Have you tried different drivers?

Tomorrow I'll try and give an info. I will also check another keyboard with oryginal din. Now Im using PS2 with adapter.

My bad, I thought it divided the internal clock.

Has anyone mentioned the "Turbo" button yet ?

Turbo is ok. Speed is eqal to dx2 in benchmark.

So what is the status now?
Everything is fast only the sound in doom is not working? Is it correct?
Did you try unisound?
