I wrote the code. :)
It would be good to print more useful messages, but the boot blocks
don't really have the space.

Brown's "Interrupt List", or any programmer's reference to the PC
BIOS, should have a list of these.
The most common ones are:
0x01 Invalid parameter
0x02 Address mark not found
0x03 Write-protected disk
0x04 Sector not found
0x06 Diskette changed
0x08 DMA overrun
0x09 DMA across 64K boundary
0x0C Invalid media
0x10 Uncorrectable CRC error
0x20 Controller error
0x40 Seek failure
0x80 Drive not ready
