Is there any beta code available for this. We have a PC104 with a 4M boot
flash from M-Systems. The vendor of the PC104 wont give us any hardware 
details on accessing the Flash and they say they are working with M-Systems
to have a driver in a month or so. We dont want to be dependent on them for
a driver.

Why would a PCMICA be any different than a Flash on a PC104 cpu card?
