6.2.4 SSD Drive Number (SW1-3 & SW1-4)

The AR-B1375/AR-B1376’s SSD can simulate one or two disk drives. You can assign the drive letter of the AR- B1375/AR-B1376 by configuring SW1-3 & SW1-4.

You can make the computer to boot from SSD by copying DOS into the SSD. If your SSD does not have DOS, the computer will boot from your hard disk or floppy disk. In this condition, the SSD BIOS of AR-B1375/AR-B1376 will set the drive letter of the SSD to the desired drive letter automatically.

The SSD BIOS will simulate one disk drive when only (FLASH) EPROM or SRAM (starting from MEM1 socket) is installed. The drive numbers with respect to the switch setting when the AR-B1375/AR-B1376 simulates single disk drives.
