Any chance you could copy and paste here that post. Some of us are no longer members of that forum. 
Yes, but this was originally written by PYM (who also showed up in this forum a few days ago so I feel like the wrong user to post this here. Please feel free to moderate and check with PYM if he can post some "sticky" thread with this info instead.
Instructions (copied from the other forum):ALWAYS BACKUP YOUR IMPORTANT WORK VIA SYSEX DUMP BEFORE ATTEMPTING ANY OS UPDATES!!
Not that we're expecting bad things to happen, but it's better to be safe than sorry. These OS updates are labelled 'Beta' for a reason; there could be something small that was overlooked that didn't get caught in our testing. Just remember, you're never going to say to yourself "Man, I wish I hadn't backed that up..."
We do not recommend using the following MIDI interfaces for sysex transfers as we have had multiple users experience problems with them:
Native Instruments Maschine
Digidesign Mbox/Mbox2
Digidesign 001/002
CME U2MIDI
If you're on a Mac we recommend using SysEx Librarian to handle the update
To configure SysEx Librarian:
In 'Sysex Librarian->Preferences':
In tab ‘General’ set ‘Pause between played messages’ to 1 second
In tab ‘Transmit Speed’ set speed to 80%
If you have trouble installing, first try setting transmit speed to alternate settings. We have had reports of speeds from 25% to 100% working for some users where 80% failed
If you're on a PC we have had the best luck with SendSX and MIDI-OX. Both are free downloads and work across the Windows line of OS versions.
To configure SendSX:
Install the beta 1.30 version, not the 1.22, to give you more options for speed settings
Make sure 'Split long sys ex messages' is off in the Options menu
In 'Options->Settings' change the speed to ~80% (1.29KB/s works well for us here)
If you have trouble installing, first try setting transmit speed to alternate settings. We have had reports of speeds from 25% to 100% working for some users where 80% failed
To configure MIDI-OX:
Install version 7; version 7.0.0.365 works great here
In View->Sysex then Sysex->’Configure…’
Set the Low Level Output Buffers to Size: 1024 and Num: 1024
Set ‘Delay Between Buffers’ to 375 milliseconds
Check ‘Delay After F7’ and set delay to 1000 Milliseconds
If the OS load countdown freezes before completing you'll need to change the buffer settings and try again
Try doubling or quadrupling the Size setting to start, and halving/doubling the number of buffers
If you experience problems loading the OS and have tried the alternate speed/buffer settings, try the other program. In some instances Send SX works where MIDI OX did not, and vice versa
To check if the OS update was properly installed, power cycle the Prophet 08. Hold down 'Global' and press 'LFO 1' to display both the Main and Voice OS version numbers.
If your OS update failed:
Update your MIDI drivers for your MIDI interface to the latest or last known stable version
Try alternate speed settings: transfer speed settings as low as 25% and as high as 100% have worked for some users when 80% did not
Try an alternate MIDI interface. The M-Audio MIDI Sport Uno works well here and is relatively cheap
In Windows with MIDI OX on Windows XP: Try doubling or quadrupling the Size setting to start, and halving/doubling the number of buffers
Search google and/or forums for the company that produces your MIDI interface to see if other users are having similar problems with Sysex transfers and whether there is a solution specific to your interface
If you are on Windows XP, try another OS or machine. Although it's not ideal, we have had less problems with Mac OSX and Windows 7. Windows XP has known issues with sysex transfers
