My first answer was deleted by another moderator.
This particular EZTRAK was one of a very narrow batch of production. The top of the flash card has jumpers that are set for a particular mother board. There were only 2 that Bridgeport used with this flash card. The flash card itself requiresd the CMOS to be set to NONE for the hard drives. A special piece of software made the flash card bootable and a very bare (limited) DOS was installed thus the reason you do not have SCANDISK or DEFRAG. The flash card was NOT a large storage device. Only 8 MB. Thus if you are loading 3D files on it, it may be full.
GP faults (general protection) are usually generated by the mother board. It could be the logic power supply, heat, software, memory, processor or the mother board. Reseat the processor, and memory. Check the logic power supply. I have even had a bad floppy drive create faults. It was the last item on my list of possibilities.
Loading the Bridgeport software does not replace the boot software nor the DOS files. another factor is that these old flash memory did not have the read write cycles of the newer DOM (disk on a module) Even the disk on a chip used by the next generation of mother boards used in these machines were known to have a short life span.
