It seems that a lot of drivers, including atapi.sys and cdrom.sys, don't
contain relocation information. You can check that using "objdump -p
cdrom.sys", which will show:

Characteristics 0x2103
        relocations stripped
        executable
        32 bit words
        DLL

Doing an "objdump -h cdrom.sys" also reveals there's no .reloc section.
This will cause the test at line 1200 of ntoskrnl/ldr/loader.c (function
LdrPEPerformRelocations()) to fail, which in turn means the driver is not
initialized. In the end, that seems to be responsible for the
INACCESSIBLE_BOOT_DEVICE.
I've tried removing the test from loader.c but that causes a page fault when
the driver entry point is called (which didn't really surprise me). The
problem thus seems to be that the relocation information is AWOL.
