Usage procedure for flash utility for NR-7700A 0. Creating a startup disk Do a floppy disk format and system transfer. Copy the all files (autoexec.bat,utilities and HEX File) to a floppy disk. Start up using this floppy disk. 1. Executing the utility After connecting to PC the drive which rewrites a firmware, PC is started using the created starting disk. DOS starts and a utility operates. 2. F/W update Automatic recognition is executed for the drive with the necessity of rewriting a firmware, and a firmware is updated. Finally please switch off power momentarily and then restart the system. The updated F/W is started. 3. Recommended environment We recommend running under the following environment. o Startup using floppy disk drive Use of the hard disk drive is possible, but we recommend starting up on the floppy disk drive because the IDE hard disk drive is using the same bus. o Use of MS-DOS ver 6.2 or higher It should be possible to use this software with a cmpatible DOS, but because the system has been built assuming MS-DOS ver 6.2, we recommend using this version of DOS. o Don't install device drivers (CONFIG.SYS unnecessary) The utility does not require any device drivers. If device drivers are installed, operation of the utility could become unstable. In particular, be sure to eliminate any disk caching device drivers (SMARTDRV, etc.). Note: Busy LED There are cases where the drive BUSY lamp continues to blink whether or not there are accesses. The conditions for this are the following. o There is a problem with the data in the flash memory. o The data in the flash memory has been read. (The blinking stops if the system is restarted.) o The data in the flash memory has been overwritten. (The blinking stops if the system is restarted.)Download Driver Pack
