Venus3 Mode - What's It Do?

It seems official: the battery in my 4040 will not hold a charge.
Lucky me, I get to deal with Meg's service.

But while playing with the Reset I found the Venus3 menu.

Press and hold the reset button, then press and holding the Power
button.

I got a blue screen (BSOD, anyone?) with the following menu choices:

Venus3 UT R06

0=WINCE Upgrade
1=GPS Tools
2=BT Tools
3=UBOOT Upgrade
4=Memory Tools
5=Other Tools
Choice: 0

To move among the choices, press Reset.
To select a choice, press Power and hold it for a long second.

Sub menues:
0=WINCE Upgrade

0=WINCE by SD/MMC (Format)
1=WINCE by SD/MMC
2=WINCE by USB (Format)
3=WINCE by USB
4=EXIT

1=GPS Tools

0=Gps Updating
1=Gps Test
2=Exit

2=BT Tools

0=BT Test Mode
1=Write BT MAC
2=Exit

3=UBOOT Upgrade

0=UBOOT by USB
1=UBOOT by SD/MAC
2=Exit

4=Memory Tools

0=ROM CheckSum
1=Memory Test
2=Exit

5=Other Tools

0=CPLD Upgrade by SD/MMC
1=CPLD Upgrade by USB
2=Read CPLD user code
3=Download & Run
4=Nand Tools
5=Nand Bad Block Check
6=Nand Ecc Check
7=Format
8=Exit



Anyone know what the CPLD user code is? Mine is ff57ff37 which is
decimal 4283957047 and binary 11111111010101111111111100110111

or:
Hex = Decimal = ASCII
ff = 255
57 = 87 W
ff = 255
37 = 55 7



Enjoy!
