RE: iPAQ flash Write-protect

Please follow the instructions, all of them, in order, none left out.
Do not use pflash before the reset after the bootldr is written to
flash.

I prefer these instructions:
ftp://ftp.handhelds.org/pub/linux/compaq/ipaq/v0.20/install.html

Go to step 14 of those instructions, do the spot check. If it looks OK,
then reboot, then check qflash. If it does not look OK or you are
worried, repeat step 12 which installs the bootldr, then do the
spotcheck, then reset, then qflash. You should also be able to oneline
help if you can connect to IRC chat at irc.openprojects.net /join
#handhelds.org

Thanks,
Jamey
