Turn CHS fields in drive table into words
...
CHS arithmetic will be done on 32-bit integers, the operand for division
of DX:AX is a word, so we save a conversion step.
Additionally, i might reuse these fields for pointing to a SYS driver later.

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.
