MOPS/586 Onboard SSD (DOS-compatible)
Expanded Memory Map
The user can convert (up to 20Mbytes) Extended Memory into Expanded Memory (EMS). The selected
Expanded Memory is devided into 16KByte pages, of which four can be mapped into the EMS-frame. The EMS-
frame is located within the first 1MByte address space and has a length of 64KByte. The start address of the
EMS-page can be selected between CC000h and E0000h in steps of 16KBytes. Most Expanded Memory
Managers are choosing their frame address location by themselves if it is not explicit set..

To be able to work with Expanded Memory under MS-DOS, you have to add the following drivers to your
CONFIG.SYS:
HIMEM.SYS and EMM386.EXE
The MOPS/586 uses a 32KByte extension BIOS (many other boards do this, too) which is mapped to a
configurable memory area. Some other kind of boards have no extension BIOS, but are using drivers which
communicate with their corresponding devices via memory mapped I/O. All these boards have one thing in
common, they have to share the upper memory area with the Expanded Memory Manager. This is often the
reason for several problems in the system. Make sure you excluded all areas in the upper memory, which are
used by extension BIOSes and memory mapped I/O. Your instruction in the CONFIG.SYS concerning the
Expanded Memory Manager should look like this: (questionmarks for location of extension BIOS)
DEVICE=EMM386.EXE X=E000-EFFF
Onboard SSD (DOS-compatible)
The onboard Solid State Disk (SSD) won’t work under any protected mode operating system, like WINDOWS
3.1, WINDOWS FOR WORKGROUPS 3.11, WINDOWS NT, OS/2 etc.
