If the console path in the PDC is explicitly set to one of the serial ports, it will not automagically change back to graphics by connecting a keyboard. The opposite is true, though: no/bad PS/2 keyboard, no/bad graphics, or invalid PDC value (ie, graphics card moved/removed) & the console will be directed to the first serial port. Do the PS/2 keyboard LED's flash and Num_Lock LED light during POST? Here's another suggestion: try removing all I/O cards, detaching all disks, disconnecting the network, and removing all but 1 pair of SIMMs. When you get the console back, you might want to enable "chassis codes" (to trace the POST codes) and disable "fast boot" (to get a better test of RAM). I believe The service manual has a table which should be able to give some indication of when the firmware chooses a console device. http://h20000.www2.hp.com/bizsupport/TechSupport/DocumentIndex.jsp?contentType=SupportManual&docIndexName=hardware+manuals&locale=en_US&prodTypeId=43563&prodSeriesId=44435&prodSeriesName=hp+Visualize+c180+workstation BTW, one of the nice things about the Allegro/Forte/Duet (4-digit B/C/Jxxxx, less J2240) systems is the LCD display which indicates where the console has be directed. Good Luck.
