The slot load Panasonic drive, with the CF card set to "slave" and I can find them both...
Disconnect the wire to pin 28, which should set the dvd drive to slave (if it was cable select) and set the CF to master, and I get checksum errors when workbench tries to load...
I have to assume this drive is internally set to master, not cable select...
However, the new, tray load HP drive, doesn't seem to let workbench boot no matter the jumper settings....
:/ and workbench is all messy from various IDE CD software being installed, setup, and messed up :p
