Try sending the reset command ("UJ" or "U;") to channel 15, then reading
the error channel message.  This should result in two different messages
depending on the ROM revision, but I only have a 1541 so I can't confirm
this for the 1581.

You won't be able to autoboot anything with a C64 unless you have a modified
kernel or a cartridge plugged in.  The support for autobooting just isn't
in the ROM.
