and the logic analyzer confirms that, with this mod, we're seeing a 2 on the bus even though U26 is bugging and trying to drive a 0.

ohh yeah, 90MHz! well, technically, 99MHz (the oscillator is 66MHz instead of 60MHz).

@tubetime shouldn't Operating System/2 Version 3 just be OS/3

strangely enough, when i connect my other type 4 complex (a 486DX2-66), i get the same DMA timeout error, so this "fix" is definitely a hack and doesn't really fix the root cause.

@tubetime always felt weird that even on IBM hardware that supports it, that OS/2 cant do an ACPI soft shutdown. Even OS/2 4.52

@tubetime Half a warped OS...

The whole IBM fumbling the Star Trek thing with OS/2 and the Warp name silliness was pretty amusing.
