VF-16
In this condition, pressing the [ENTER/YES] key one more time would initialize the recognized disk drive. This mode
puts the disk back to the condition originally formatted.
4-6. Flash ROM
This mode is used when copying the system software from EPROMs to Flash ROM. As mentioned in the section “3.
SOFTWARE UPDATE” (page 8), the VF-16 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 VF-16 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. Power off the VF-16 and disconnect the AC cable from the AC IN socket.
2. Plug the VF-16 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 panel assy by loosening screws on both sides and on top, so that the ROM CARD PCB assy can
be vertically plugged into the 50-pin connector J5 on the MAIN PCB assy.
4. Connect the AC cable and power on the VF-16.
In this condition, the VF-16 is booted up using the system software inside the EPROMs. The next procedures to take
are as follows.
5. Put the VF-16 into the Service Mode, rotate the jog dial and select “FlashROM” menu.
4-7. Free Block Check
This mode is used to check the condition of the diskette inserted into an external SCSI drive connected to the VF-16 or
the internal E-IDE hard disk drive. The drive to be checked is the one currently selected by the SETUP menu
“Drive_Sel?”.
Then, press the [ENTER/YES] key.
The display indicates the following and “SURE?” will start blinking.
6. Press the [ENTER/YES] key to copy the system software from EPROMs to Flash ROM. The display shows
“Erase ROM”, “Write ROM” and then “COMPLETED!” in order.
7. In order to confirm that the VF-16 is correctly booted up using the system software inside the Flash ROM, power off
the VF-16, disconnect the ROM CARD PCB assy and power it back on again.
8. After confirming that the VF-16 is booted up using the Flash ROM, referring to the section “3. SOFTWARE
UPDATE” (page 8), update the system software inside the Flash ROM through SCSI port to the latest one.
