Remote Enabler; Cable Definition (Dsub-9Pin-Female) - DIGITAL-LOGIC Microspace MSM586SEN Technical User Manual

DIGITAL-LOGIC AG
When video redirection is enabled (option NOVIDEO not active), the BIOS will skip the initialization of both
ISA and PCI VGA cards. The BIOS thereby comes up much quicker. Using the keyword DUALVIDEO will
enable possible VGA cards as well and display video output on both the real video card and on the remote
machine. This allows hardware engineers to debug vga controller problems.
The BIOS will not warn for missing keyboards as soon as remote keyboard is enabled.
You can leave REMHOST by pressing the left SHIFT and STRG keys simultaneously.
