Rename rdos.sys to rdos.bin
...
*.sys is meant for DOS-like driver binaries. I actually have a flat
binary with a specific load offset.

Run kernel with from offset 0
...
I try to get the interrupt handlers into a offset as low as possible.
This is necessity if i want to relocate it later on its own.
For running from HMA, a minimal offset of 16 bytes would still be
necessary.
