Hi, FWIW, if I disable the embedded serial port, and set the virtual serial port to COM1, this setup works. Which is fine, for most machines, except the odd cases where I like to use the serial port and log output over time (I prefer that instead of VSP then). The BIOS changes needed: rbsu> SET CONFIG EMBEDDED SERIAL PORT 4 Embedded Serial Port 1|COM 1; IRQ4; IO: 3F8h-3FFh 2|COM 2; IRQ3; IO: 2F8h-2FFh 3|COM 3; IRQ5; IO: 3E8h-3EFh 4|Disabled <= rbsu> SET CONFIG VIRTUAL SERIAL PORT 1 Virtual Serial Port 1|COM 1; IRQ4; IO: 3F8h-3FFh <= 2|COM 2; IRQ3; IO: 2F8h-2FFh 3|COM 3; IRQ5; IO: 3E8h-3EFh 4|Disabled rbsu> SET CONFIG BIOS SERIAL CONSOLE PORT 3 BIOS Serial Console Port 1|Auto 2|Disabled 3|COM 1; IRQ4; IO: 3F8h-3FFh <= 4|COM 2; IRQ3; IO: 2F8h-2FFh rbsu> SET CONFIG BIOS SERIAL CONSOLE BAUD RATE 9600 BIOS Serial Console Baud Rate 1|9600 <= 2|19200 3|57600 4|115200 Bye, Anders.
