Title: Dataflyer autoboot ROM
Post by: simono71 on June 03, 2010, 09:24:26 PM

Hi,

I was 'playing' with my dataflyer (SCSI version with no memory header) and seemed to have screwed up the autoboot ROM. (I was hooking it up to my logc anaylzer/oscilloscope).

The system works fine, but will no longer autoboot. I keep getting inconsistent reads of the boot rom with my eprom programmer, telling me I screwed it up somehow.

Does anyone have a dump of the Dataflyer 1.9 rom by any chance so I can re-image the rom?

I have a dump of my DataFlyer 2.0 boot rom. It's IDE only version but the boot rom may be the same.

I still have to learn how to make a dump rom file, but I have a  scsi dataflyer500 and the autoboot chip sticker says DF Autoboot Ver 2.0 - 256
The board is dataflyer plus revision 2.3

Any of those above would be awesome.

The boot rom basically contained the hard drive driver software. As the board could be configured either way (ide, scsi or ide and scsi) it would make sense to me that they would put both drivers into the boot rom, instead of supporting different roms, but who knows. Perhaps the ide only board only came with the ide driver burned into the rom.
