You are great. I flashed builder_bigdisk_v21.upgrade and then immediately applied hijack_v525+.zImage before rebooting. Everything came back fine, no error messages, at least on the VFD wink

I loaded a few albums and changed a few config.ini items via emplode without issue, sync'ing several times.

Here is a boot log, for good measure...everything looks dandy to me:
Code:
empeg-car bootstrap v1.02 20001106 (hugo@empeg.com)
If there is anyone present who wants to upgrade the flash, let them speak now,
or forever hold their peace...it seems not. Let fly the Penguins of Linux!

Gotta update that timezone hahaha

Next, I think I will attempt to load all of the fids/dyn_data via USB-PATA adapter/linux and see how that behaves.

I will reply back with results cool

Cheers!
