Hi,

i have a mini 2440 with 7" lcd. i installed wince image via sd card with
the options below.

#This line cannot be removed. by FriendlyARM(www.arm9.net)

USBMode = No
Action = Install
OS = CE6
VerifyNandWrite = Yes

LowFormat = No
Status Type = Beeper| LED

# Linux part

#User Bin part
UserBin-Bootloader = Superboot2440.bin

before this install i used nboot as bootloader. i had problem with yellow
progressbar and i changed the bootloader to superboot2440 file. now the
image installed successfully.

my first problem is this image deletes all files and settings sometimes. 
second and the biggest one is when i try to install new image with sd card
nothing happens. nor menu does not appear. no leds and no beeps. 

please help me
