sys: fix gcc build, int86 has to preserve ds
...
The int86 function is used to call interrupt 21h
service 32h in the reset_drive function. This
function returns a pointer using the ds register.
ds will usually point into the DOS data segment
then (for our kernel). However, the compiler
assumed ds to be unchanged.

fix OW warning W115
...
cast array using pointer to first element [newboot] instead of pointer to whole array [&newboot] to avoid OW error W115 "&array may not produce intended result" since the address of operator "&" is not required for getting the address of an array.
