5.1.5.4 Example for Generating a ROM-Silicon Disk with FLASH-PROMs

by Means of the MS-DOS-RAM-Disk:

Goal: On the silicon disk board, an FLASH-PROM silicon disk with a capacity of 2MByte

(consisting of eight 256KByte FLASH-PROMs (2MBit FLASH-PROMs) should be

generated started with the base address C0 0000hex.

A silicon disk board with eight 256KByte FLASH-PROMs (2MBit FLASH-PROMs) is used.

The base address is set to C0 0000 hex and to a length of 2MB.

The system is booted from hard disk (drive C:). The programs SDROM.SYS, SDGEN.EXE and

SDLOAD.EXE (in the subdirectory C:\SD) and a text editor are required for the generation.

The following lines are input at the end into the file C:\CONFIG.SYS via the text editor:

DEVICE = C:\DOS\RAMDRIVE.SYS 2024 512 64 /E

DEVICE = C:\SD\SDROM.SYS base=/C0 size=/2048

The system is re-started by pressing at the same time the keys <CTRL>, <ALT> and <DEL>.

At the runup, the system outputs i.a. the following messages:

Microsoft RAMDrive Version x.y - virtual drive D:

disk size: 2042K

sector size: 512 Byte

block size: 1 sector

directory entries: 64

ROM SILICON DISK installed as drive E:. Vx.y date

The drive D: is used as master for the ROM silicon disk. For this purpose, first the label must be

removed as this occupies a space required by the operating system. The respective command is:

LABEL D:

Then the following message is displayed:

data medium in drive D is MS-RAMDRIVE

data medium label (11 characters, ENTRY KEY for none)?
