It looks like the VSP is not getting described in ACPI when configured
the way you have it. Have you tried Enabling EMS Console? Perhaps
that will cause VSP to be enabled in ACPI.

To ease the configuration of the Virtual Serial Port, I was thinking the
best way to do it was to set up VSP on COM1, and have the external
serial port be COM2. In rbsu (this is on a DL 360 G5), I set this:
rbsu> SHOW CONFIG SCRIPT
SET CONFIG Embedded Serial Port COM 2; IRQ3; IO: 2F8h-2FFh
SET CONFIG Virtual Serial Port COM 1; IRQ4; IO: 3F8h-3FFh
SET CONFIG BIOS Serial Console Port COM 1; IRQ4; IO: 3F8h-3FFh
SET CONFIG BIOS Serial Console Baud Rate 9600
SET CONFIG EMS Console Disabled
Then, I only need to add a /boot.config with the -h option, to boot with
a serial console.
With this setup, the boot loader and kernel shows the output on the VSP
just fine. The terminal on ttyd0 does not show up however, I get no
login: prompt. In dmesg.boot, there is only:
sio0: <Standard PC COM port> port 0x2f8-0x2ff irq 3 flags 0x10 on acpi0
How come the VSP COM1 port on 3f8 is not found? Did anyone run into
If I set up VSP on COM2 as is the standard thing to do, everything works
fine. But then I have to recompile the boot loader (eeeew!).
