Haven't seen this reported so it may be unique to the HP dc7800. Or maybe its just obvious that this is a bad idea and nobody goes there. Anyway, when booting my dc7800 from a flash drive:
- if "EHCIacquire=yes" Chameleon starts but hangs after a bunch of EBIOS device timeout errors. Naturally, the same thing happens for "USBBusFix=yes".
- If "UHCIreset=yes" then the system will boot but the USB keyboard/mouse are NFG.
