32bit Cardbus CF adaptor

[Mark Lord]

Dan,

I saw your message on linux-pcmcia.
Today I purchased a Delkin Cardbus CF adaptor
similar (identical?) to yours.

It is definitely ATA -- the standard ATA register file
is at I/O offset 0x10 from the I/O base address, and I can
indeed read/write sectors etc.. using those ports, but at
moderately slow speeds.

I think we need more info to figure out how to turn on prefetch etc..
to get the higher transfer rates used in the Windows drivers.

One thing that would be very useful to me, would be a register dump
of the I/O ports *after* the windows driver has initialized them.
Any ideas on how to do that?

Cheers

Thanks a lot. I will get one and try.
The adaptor is in fact developed by ASKA corp in Japan, and there is
a little more information on the site
