pwlconfig has an option available which will create 2 partitions on the 
target device, a bootable  FAT partition with kernel and an ext2 partition 
with an uncompressed filesystem which is copied into a RAM disk at boot 
time. This option should work with the DOC.

I have never tried running pwlconfig on the same platform as my target, so 
I never attempted to actually have pwlconfig load a filesystem onto an 
attached DOC. I always used the intermediate step of loading a CF and 
moving files from it to the DOC once its running on the target system.

I think /dev/fla or /dev/msys/fla should work. pwlconfig works on the 
complete target device, not a single partition. It will use fdisk and 
filesystem tools to prepare and load the device.

Not sure, it's been a while since I manually tweaked syslinux.cfg. 
pwlconfig should do all that for you...

Yup, been there, done that. In my opinion getting DOC to support an ext2 
filesystem to boot from is nothing short of a nightmare. I would avoid 
that scenario at all costs. Keeping the bootpartition FAT and using 
syslinux should be quite doable and fairly easy to reproduce once 
succeeded.

BTW, I think you had asked me to be added to the PWL mailing list. I just 
added you manually. Hope this is ok.
