I have 2 debut 2-port digital with sandisk 128mb compact flash. I can take the flash card with all files and move from one mother board to another and both work fine. When I copy the contents from the good flash card to another identical 128mb sandisk and install it on either mother board it won't boot. Any ideas?

Hookup with hyperterminal and watch the progress. I'll bet you'll see missing shell or command.com. Have never been able to just copy from one flash to another.

It's not supported by Verticle / Comdial either. There is one person on this board who has had success doing it, but it is a complicated process(to me anyway) and it involves properly formating the blank disc.

Please complete your profile Robert so that we know who we are helping. If you are a Comdial dealer then the repair files can be pulled from the CCC. They can be transferred to the CF card and you're back in business.

Mark K. and Rather be Fishing are correct about the card. Newer versions of Windows will not properly format a flash card for booting. Last version which does that operation correctly is Windows 98. If you have that version, you can format the card as a bootable drive and then transfer the files. This is if you have a flash to IDE converter and can boot to DOS from a floppy drive. If not, you will need to have someone format the flash card for you. I could help with the card format if it comes to that. Also, there is another thread on the board that tells how it was done at this address: https://www.sundance-communications.com/forum/ultimatebb.php?/ubb/get_topic/f/16/t/000536.html

OK further testing. Pulled out a new 512K CF card. Ran the utility on the Comdial board for the DX80 7271C Vmail. Worked like a champ. 36 hours storage too. Deleted all files and transferred Debut files. Also worked great. Rather than spending an inordinate amount of time reinventing the wheel I recommend using the established methods from the tech support board. I remember having to use a Win 98 machine and using a specific rev of Ghost to do the disk copy and it seemed like a bigger pain than it was worth. Making multiple copies to stock trucks so that techs can restore DOA out of warranty mails in the field.
