3. SOFTWARE UPDATE

Since the 8Mbit flash ROM is mounted on the MAIN PCB assy, the D1624/D824 software can be updated through the
SCSI port. Please refer to the following explanation for correct software updating procedures.

3-1. Required Tools

The following tools/equipment are required to update the D1624/D824 software.

1. IBM PC/AT compatible computer with SCSI board

2. Removable type SCSI drive

3. Cable between the removable type SCSI drive and the SCSI board

4. Cable between the removable type SCSI drive and the D1624/D824 (D-SUB half-pitch 50-pin)

5. A Utility software to extract the WinZip compressed file

3-2. Software Updating Procedures

Presuming that the updated software is correctly sent to you via email and is copied into your computer.

1. Connect the removable type SCSI drive to the IBM PC/AT compatible computer SCSI port.

2. Insert the diskette to the removable type SCSI drive and format it by the computer on which Windows 95/98 is
running.

3. Using the utility software, extract the WinZip compressed software file. The extracted file name is “d1624mvX.XX”.
(X.XX indicates the version number. For example, if the software version number is V1.06, the file name is
d1624mv1.06.)

3. Copy the updated software file “d1624mvX.XX” to the removable type SCSI drive (diskette).

4. Set the removable type SCSI drive ID to 6 and connect to the D1624/D824 SCSI port (D-SUB half-pitch 50-pin).

5. Turn on the power of removable drive and then D1624/D824.

6. Insert the diskette with updated software file.

7. The D1624/D824 automatically finds the software update file in the SCSI drive/disk and is put into the software
update mode. In this condition, “SystemUp” is displayed and “SURE?” is blinking on the FL display.

This mode is used when copying the system software from EPROMs to Flash ROM. As mentioned in the section “3.
SOFTWARE UPDATE” (page 11), the D1624/D824 software inside the Flash ROM can be updated through the SCSI
port. However, if something wrong happens when updating the software (e.g. A blackout occurred while updating the
software.), the D1624/D824 might not be able to boot up using the system software inside the Flash ROM.
In this case, the following procedures must be taken.

1. Turn off the power of D1624/D824 and disconnect the AC cable from the AC IN socket.

2. Plug the D1624/D824 EPROMs into the ROM CARD PCB assy sockets (U1 and U2). The SW on the ROM
CARD PCB assy must be set to “EPROM” side.

3. Open up the top cover, loosen 4 screws fixing the HD bay to the HD bracket and move the bay to the front side,
so that the ROM CARD PCB assy can be plugged into the 50-pin connector J5 on the MAIN PCB assy vertically.

4. Connect the AC cable and turn on the power of D1624/D824.

turn off the power, disconnect the ROM CARD PCB assy and turn the power back on again.

8. After the boot up confirmation, referring to the section “3. SOFTWARE UPDATE” (page 11), update the
system software inside the Flash ROM through SCSI port again.

4-9. Free Block Check

This mode is used to check the condition of the diskette inserted into an external SCSI drive connected to the D1624/
