2.3.3 Setting up an EPROM Disk
EPROMs should be inserted starting from Socket. All modules have to be of
the same type.
To create a ROM disk you will need the following:
- EPROM devices
- EPROM programmer
- ROM files
The ROM files are hacked-up portions of your system and program files that
should have the same size as your EPROM devices.
On the utility disk you will find a program called: ROMIMAGE.EXE that will
assist you in creating these files. Before using the program there are some
files you will have to prepare first:
1. The system files, for example MSDOS.SYS, I/O.SYS, COMMAND.COM
The program can pick these files up automatically from your boot deviceor
from a bootable floppy.
2. Your application files and other necessary DOS files. Make a subdirectory
that only contains these additional files. With “other DOS files” are meant
files such as AUTOEXEC.BAT, CONFIG.SYS, EMM386.EXE etc
3. Prepare a directory that can temporarily hold the generated ROM files
Once you prepared all the above, start the ROMIMAGE.EXE programSystem
driver :
location of system files (see 1)
Source path: location of program files (see 2)
Destination path: this is where the ROM files go (see 3)
EPROM-size: depends on your choice
Simulation-disk: set this to the drive letter the ROM disk should emulate
After you have set all the right directories, use the Analysis file function to
let the program determine how many files of what size it should generate.
After using the Analysis function go to Create image, and generate the
ROM files. Than exit the program. In the directory that was assigned to hold
