I found different flash card writers make all the differance. I just copied and pasted, but you need fresh data.

Some CF cards might have a DOS block size of 2048 on the larger cards. Reformat them to a block size of 1024. Also the DOS partition must be set to active.

The 8511b.exe works well but I have a zipped up file I use that already has the changes in the trans.txt and vm.cfg for the DX120. It's fast and easy.

Bill,

Besides the changes in trunk numbering and modem extension number, what other changes did you have to make?

All I really did was the trunk numbering, max password length and the DX80 link commands for backplane integration.

Usually I don't do the backplane integration because of port lockup issues. I don't know if that's been fixed in F19 or not. I suspect it hasn't.

Really there's no advantage to my zip file over using 8511b since the changes are so easy.

Bill,

I believe the port lockup went back even to the DX80, where if you used backplane integration, you had to be careful what you did with the MWL, in regards to who had it and who didn't. I got around that by using the inband string for MWL, and still used the backplane integration, but ONLY for the purpose of synching the clock. That seemed to work pretty well, and got around the problem where certain cases of mailboxes have the Sx entry would cause lockup.

Is that not the lockup you were referring to?

Incidentally, I just changed out a CF on a Debut. I first tried a new 128MB SanDisk CF, but no matter what I did the Debut wouldn't see it. I then tried a new PNY (volume was labeled as TOSHIBA-something) 512MB CF, and it worked great. As far as CF units go, out of the box they must have different formats, as far as cluster size, or something. Both of the ones I tried showed up in Windows (XP) as being formatted FAT. Any idea as to the difference, or how to get around it, i.e., reformatting? Can the reformat be done effectively from XP?
