If you are receiving a new Axim x51v, it may already have A06 on it. To check this out, click on Start, Settings, System information.
A01 is the original ROM.
If there is nothing on the PDA, then just download the A06 ROM from Dell at:

Process of upgrading the ROM
1) If you have some application data on the PDA, back it up by copying the files out.
2) Sync the PIM data with Outlook.
3) Upgrade it and resync with Outlook to re-upload the PIM data.
4) Reload any Applications and the data
Flashing the ROM essentially over-writes your OS, and all files on your PDA. It will NOT overwrite files on your Flash Card, however, but applications on it may need to be re-installed.
