DENEB booting off of a thumbdrive.

[MozzerFan]

I also own a deneb, and I have successfully booted from a usb thumb drive and a sd card. I didn't have to do anything special. I just put all poseidon related things in the flashrom and partitioned and formatted the drives with SFS.
Works like a charm. I didn't have to change anything in the settings.

Tell me what steps you went through to setup your deneb.

I installed the deneb card and booted my system in rescue mode. Then I installed poseidon and luciferin. I then powered off the system and removed the rescue mode jumper and powered on. I set up the correct deneb driver in trident (in my case the dma driver), clicked the online button and saved my settings. Then I started luciferin, cleared the flashrom, and flashed it again with the related poseidon files (using the quick poseidon menu option from luciferin). [EDIT: forgot to mention that I removed psdstackloader from user-startup]. I partitioned and formatted the thumb drive with SFS, copied some system files to it, and rebooted my system from the thumbdrive. Like I already said, it worked like a charm.

What I found out the one time I got it to work was that the thumbdrive had to be the ONLY usb device plugged in.

It sounds like a power problem to me. Are you connecting the thumb drive to a self-powered hub? I do.
Are you using the Z2 deneb device driver?
Also what you could try is to remove some expansion cards
and see if it makes a difference.

Hi Bash, just remembered something important. Firmware v7 of the deneb comes with a watchdog. This means when in a short amount of time to many reboots are taking place, the deneb flashrom will be deactivated. If you have v7 and you try to boot from thumbdrive, wait about 10 seconds before rebooting. Otherwise the deneb flashrom is deactivated and poseidon will not be started, so the system can't boot from your thumbdrive. The new firmware on the E3B website doesn't have the watchdog thing anymore, so if you're uncomfortable with the watchdog thing, you can reflash the deneb with the new firmware.

Also check your PSU. You have many expansions in your A2000 (lucky you). Maybe your PSU isn't providing enough juice.

Sometimes it's necessary to change the startup-delay for the usb device in trident prefs, otherwise the device won't be seen in the boot menu.
