Subjectre: [preview] VIA IDE 4.0 and AMD IDE 2.0 with automatic PCI clock detection

Content-Type: text/plain; charset=us-ascii

I've tried out your new via driver and it
appears to have solved the problem with
the mis-detected ls-120 drive, but the ata66
drives are still being run at 33.

More interestingly, the pci-clk calculations
seem to be returning badly off values.

My motherboard is a kt133a+686b btk7a from abit.

When I set the FSB to 133 with PCI=133/4=33 the
timing code returns 43mhz.

when I set the FSB to 100 with PCI=100/3=33 then
it returns 42mhz.

These are scarely different from the nominal values.
I didn't observe anything bad in the few minutes
I was running like this, but right now I've hacked
the driver back to a hardcoded 33.

What should I do next?
