You can install hard drives and even IDE cdrom drives with no problem without getting into the bios, the bios IDE drive types are set to auto-detect. The boot order is set to boot from CDROM first so you can even boot off a IDE cdrom if it's attached.
There really isn't a lot you can do in the bios, most of it's power management. You are not missing out on a lot by not getting into the bios.
The VGA port works fine (it's the 10 pin header nearest to the CPU) and doesn't require any changes in bios. The cable needed is the same as the i-Opener one, search in the IO sections for VGA cable pinouts and you should be able to find the pinouts.
