6.2.3 SSD Firmware Address Select (SW1-2)

The AR-B1375‘s and AR-B1376’s SSD firmware occupies 8KB of memory. SW1-2 is used to select the memory base address. You must select an appropriate address so that the AR-B1375 or AR-B1376 will not conflict with memory installed on other add-on memory cards. Additionally, be sure not to use shadow RAM area or EMM driver’s page frame in this area.

Table 6-2 SSD Firmware Address Select

If you are not going to use the solid state disk (SSD), you can use BIOS setup program to disable the SSD BIOS. The AR-B1375 or AR-B1376 will not occupy any memory address if the SSD BIOS is disabled.

If you are going to install the EMM386.EXE driver, please use the [X] option to prevent EMM386.EXE from using the particular range of segment address as an EMS page which is used by AR-B1375/AR-B1376. For example, write a statement in the CONFIG.SYS file as follow: (If the memory configuration of AR-B1375/AR-B1376 is C800:0)

DEVICE=C:\DOS\EMM386.EXE X=C800-C9FF
