[iPAQ] bootldr CF inconsistency + bug

Hi,

I've been experimenting with bootldr-2.18.43 and 2.18.44 on an iPAQ 3660.
I have a single and a double PCMCIA sleeve as well as a 64MB CF card.

I've put the appropriate files on a dos and ext3 partition on the CF card,
and have succesfully booted into linux.

2.18.44 didn't work because it appeared to be reading the wrong sectors
for my 'boot' directory. It was reading 8 sectors beyond where it should
have been. Going back to 2.18.43 fixed this. I note from the diffs that
there was an explicit patch to change some sector offsets -- is it
possible that it's only correct for particular fat filesystems?

Having had success with the single sleeve, I tried the dual sleeve. It
recognised the sleeve and card but started failing when trying to execute
'vfat mount'. A typical result is included below.

I then went back to the single sleeve, but it no longer seems to work.
The sleeve is identified but the disk info seems to be fairly random.
Sometimes it gets as far as starting to boot, but the kernel hasn't been
loaded properly so I get 'invalid compressed format'.

Can anyone advise as to what could be the issues? Any suggestions as to
other things to try?

PS: Having written the above, I've managed to get it to boot again, this
time using a different dual sleeve. Could there be some issue with battery
levels in the sleeve? The iPAQ is in the serial cradle with power all the
time I'm doing this.

Thanks.
