5.2.4 SSD Drive Number (SW1-5 & SW1-6)

The AR-B1474 SSD can simulate one or two disk drives. You can assign the drive letter of the AR-B1474 by configuring SW1-5 & SW1-6.

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-B1474 will set the drive letter of the SSD to the desired drive letter automatically.

The AR-B1474 would simulate a single 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-B1474 simulates single disk drives.

SW1-5	SW1-6	Occupies floppy disk number (SSD)
OFF (*)	OFF	0 or 1 (Note 1)
ON	OFF	0 or 2 (Note 2)
OFF	ON	0
ON	ON	0

Table 5-3 SSD Drive Number

NOTE: 1. If there is no DOS on this SSD, the disk number will 1 (B:). If any DOS is found by the AR-B1474 SSD BIOS, the disk number will be 0 (A:) But, you can change the disk number from 0 to 1 by pressing the <ESC> key during system bootup.

2.If there is no DOS on this SSD, the disk number will be 2 (C: or D: or … ). If any DOS is found by the AR- B1474 SSD BIOS, the disk number will be 0 (A:). But, you can change the disk number from 0 to 2 by pressing the <ESC> key during system bootup.

(1)Simulate 2 Disk Drive

When (FLASH) EPROM and SRAM are both used on the AR-B1474, or you only have installed SRAM that does not start from MEM1 socket, the AR-B1474 will simulate two disk drives. The drive numbers respect to those switch settings when AR-B1474 simulates two disk drives.
