d1dab01633 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.

cd7aafde09 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.
