I have used a VersaLogic VSBC-6cr and a Densitron DPX70. The
Densitron has a few more features but the VersaLogic seems to be a
more stable board. rtLinux on the 2.2 series with the M-Systems DOC
driver works great. The directions for booting the system must be
followed to the letter. The ROM extention in the DOC will interfer
with loading the linux kernel and needs to be disabled during install.
Check with Documentation from M-Systems for the procedure.
The only drawback I have found with the VSBC-6 and the DOC is the Rom
Socket on the VSBC-6 is under the PC/104 bus and the 72Meg DOC will
not fit with a PC/104 card installed (its to tall).
