Athlon/Athlon XP CPUs, the
Super I/O controller is a VT82C686B ...
When I test the 5.25" drive I see a pass at 300k
DD (with a 360K disk)
but with the 1.2MB disk I see three failures. I was expecting 500k DD
to pass with a 1.2MB disk ... am I wrong?
I sent Dave about a dozen MB tests that I did on various MBs recently.
There was one case where 1.2MB 500k DD failed, but read/wrote in DOS.

Unfortunately, (and the VIA Super South Bridge) is one of the cases,
the integrated FDC can be configured about six ways till Sunday,
including PS/2 mode. DOS function will always work because DOS uses
the BIOS routines to access the drive--and the BIOS knows all about
the weirdnesses of the support chips.
OTOH, the VIA SSB chip has a neat mode allowing for interface to a
floppy drive using the parallel port.

Interesting - I've done that with a Dell laptop, but I didn't know
there was a desktop chipset that could do it.

The line has blurred between "laptop" and "desktop" chipsets--the VIA
SSB has several features that are cutomarily associated with the
former. Given that laptops/notebooks are gradually displacing
traditional desktop machines in the consumer market, it makes sense
to produce a chip that has laptop design features but can be used in
a desktop system.

Chuck
