THANKS GUYS, Maybe I just do not have the brains <smile>. Here is the read me txt. It is actually from the 1.05 version but after unpacking the 1.06a version it gives the exact same read me. The main difference at least in operation is that 106 runs a batch file. So that you do not have to make the startup disk with the autoexec, etc... files. The batch file does all the copying of the needed files and then upgards the firmware but then leaves you in true DOS. I amy be able to run it from the CMD prompt within the win enviroment but it seems that the read me says that it won't work to good that way.
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.)
