Error '3' happens when the sector that is read doesn't end in 0xaa55.
The mbr_bootsel code in -current loops after any error.

One possibility is that the sector is being read using CHS - but
the add in card is using a different mapping.
Alternatively it is trying to do an LBA read and the card bios
only supports CHS ones...

I fixed a few 'bugs' in the mbr_bootsel code - it will also
redisplay the menu after any error.....

You might find that copy works....

It boots win98 - which OS won't it boot?
Fixing it requires disassembling the pbr to work out what it expects
(and maybe the mbr for something that will boot it)
