Make sure you are not trying to use a faster speed than the test program recommended Also note that the test program tested the transfer speed to a single emulator If you are daisy chaining several emulators their combined load can slow down the printer port rise times resulting in a need to further slow down the transfer speed to avoid over running the port signals Try the next slower transfer speed DO is the fastest speed D2 is the slowest speed A print spooler or TSR is interfering with our port accesses Try booting clean from a DOS diskette to see if things stabilize If this corrects the problem suspect that some other program like a print spooler is interfering with our access to the port EconoROM II User s Manual 8 Copyright 1996 TechTools Printer port set to an incompatible mode If your printer port is configurable through BIOS settings Check that these are set to STANDARD AT NIBBLE or COMPATIBLE mode Avoid ECP EPP PS2 HIGH SPEED or similar settings Failed to use a W16 parameter to load to a 16 bit emulator The loader treats a 16 bit emulators like two daisy chained 8 bit emulators If you fail to specify the W16 parameter the loader will load the entire file into the upper 8 bits ONLY If the file is greater than 1 2 of the emulator s capacity it will fail verify Note that if the file is relatively small it will pass verify but still be wrong Verifies but target does not run Targe
