[Soekris] Can't seem to boot after flashing BIOS

[Falcor]

I have a 4801 and updated the BIOS from 1.21 to 1.28.  The box worked 
perfectly with the 1.21 bios, but I needed to update it for some testing 
with new code.  I have been booting off of a CF card.  Now when the 
soekris boots the bios and reports:

"No Boot device available, enter monitor."

My current config looks like this:

 > show

ConSpeed = 19200
ConLock = Enabled
ConMute = Disabled
BIOSentry = Enabled
PCIROMS = Enabled
PXEBoot = Enabled
FLASH = Primary
BootDelay = 2
FastBoot = Disabled
BootPartition = Disabled
BootDrive = 97 0B 00 00
ShowPCI = Enabled
Reset = Hard

So many of these are new and undocumented in the online manuel.  Any 
idea if the Boot Drive is set correctly, and if not what should it be to 
have it check the CF card?  Thanks!
