∙Don't power off the system while the program is running. EPROM.EXE notifies you as it completes various steps of its operation, but it is not finished until it says so. If you power off in the middle of EPROM.EXE the contents of the EEPROM may get erased or garbled.
∙When the program is done, you will be returned to the DOS prompt.
∙If you also received a new ADF file, reconfigure the system following the procedure listed previously.
∙Reboot the system so that the MCMaster will be properly initialized with the new ROM code. If your update includes a new ADF file, it's a good idea to force reconfiguration even if you don't intend to change anything.
You can force reconfiguration by running configuration, changing any option and changing it back again. When you save the configuration, the new ADF information gets stored in the system's nonvolatile memory.
If, for some reason, the new code doesn't work as expected, you can recover the old code by running EPROM.EXE again with the old hex file. You can find the ROM code your MCMaster was shipped with on the option disk that came with your system.
MMPIDD.SYS MCMaster Device Driver
The chief use for this device driver is to allow a "delayed" startup of the MCMaster in conjunction with a
iInstall a cache toggle. Pressing the [SYSRQ] key will turn the MCMaster's onboard cache off or on.
rRelocate resident interrupts. Interrupts 15h, 13h, 75h, and 4Bh get moved from the top of conventional memory to lower memory in the device driver. This is helpful with some programs, such as Windows, that have trouble dealing with memory between the end of low memory and the extended BIOS data area. It also looks for EMM386 and, if it finds it, allows it to work properly with INT 4Bh calls. This switch may also be required if the MCMaster is being used with other busmastering adapters.
