568 Appendix A Command Reference

VTOF

Vdram transfer To Flash

Class

Description Transfers the current contents (no matter what they are) of the video frame buffer to the

Flash EEPROM (if equipped) used to store the operating system firmware.

EPROM data sent to the generator is normally stored temporarily in video VDRAM. If the

file transfer is successful, a loader code segment will be placed in CMOS SRAM and

jumped to. This code segment will, in turn, transfer the image of the firmware in VDRAM to

flash memory, thereby replacing the entire flash memory contents. Following this, the

generator will reboot and re-initialize using the new firmware.

Important: Improper use of the VTOF command will cause permanent malfunctioning of

the video generator.

The VTOF command should be executed only by the Quantum Data ARCHIVE.EXE utility

as part of a firmware update operation. On stand-alone generators, the ARCHIVE.EXE

utility first copies the new firmware file to the video frame buffer via the serial port. Once

the file has been successfully copied to the buffer, the buffer contents are then used to

update the Flash EEPROM.

Executing the VTOF command when the video frame buffer does not contain a valid

firmware file will cause a permanent malfunctioning of the generator. There is no way to

restore the firmware on stand-alone models via the serial or GPIB ports once this has

occurred. The stand-alone generator must be returned to Quantum Data or a Quantum

Data authorized repair center for reprogramming.

Note: The firmware may be replaced at least 10,000 times. After that, the generator may

require service to replace the flash ROMs.

Important: In the unlikely event the power fails while the loader is transferring data from

VDRAM to flash memory (this process taking approximately 20 seconds to complete), the

generator will appear to be inoperable at the next power-on. To restore operation, the

generator must be removed from the system, opened, connected to a computer having a

special adapter, and reprogrammed from a binary image file using a special executable

program.Is this something the customer can do himself? Or should we advise him to return

the generator to the repair center?
