Enter the following command at a DOS prompt to start low level formatting:
memcform <paraml><param2>
Enter “S” for param1 to format a SRAM-Module or “F” for a Flash-Memory.
Entering “Z” for param2 will start the formatting without any further user input
(if possible).
After low level formatting the computer must be rebooted for the changes to
take effect.
GetMem Device Driver
The BIOS extension requires the getmem driver which provides BIOS expansion
memory (about 600 bytes). Add the following line to your config.sys file:
device=getmem.exe
DOS Formatting
The silicon disk can now be prepared for use with the fdisk and format DOS
programs. If a hard disk drive is installed in the system, make sure that fdisk is
pointing to the appropriate disk (option “5”).
The silicon disk is not entered into the CMOS-RAM. No additional
controller(such as an IDE-Controller) is required to use the silicon disk.
Reorganization
If the silicon disk is predominately used for read operations, access times can pos-
sibly (depending on the disk size) be improved by reorganizing sector ordering.
Use the memcform program to start the reorganization process:
memcform rs
Do not use any other method but the ESC key to stop a
running reorganization process. CTRL- C or a system reset may
result in data loss.
After stopping the reorganization using the ESC key, the cur-
rent segment and possibly one more segment are processed be-
fore the program stops. This might take up to 2 seconds. The
program can then be restarted to resume the reorganization.
Additional Considerations
The segment D0000 — D3FFFF is used by the BIOS extension as a window to the
memory module. Therefore this segment needs to be protected from accesses by any
other program. This segment range should therefore be excluded when installing a
memory manager such as emm386.
