He wondered if the other machine was providing a login: msg or similar. Well, I have the same machine and the serial port is attached to a serial printer (Epson FX850). If the printer is plugged in then, as Peter experienced, the POST menu (hwd stuff) grinds out one character every few seconds until done or I have had enough. Unplugging the printer lets it zip through at normal speed. My best guess is the Phoenix Bios in the machine is very unhappy with signals being asserted on the serial port during POST and eventually times out to progress. But why should it work so slowly through the entire boot up screen?? The printer is not sending anything. Intel itself made the motherboard, with it's embedded serial ports. Joe D.
