Hello,

In section 2.2 Calling conventions of the PCI BIOS for Atari, it is
written:

--8<--8<--
The routines may modify only those registers which are used to pass
parameters or to return information in as specified for the specific
function, plus the status register.
--8<--8<--

For me, any function of the PCI BIOS *MUST NOT* change any register not
listed in either input or output parameters list, or as output value.
Do I understand correctly?
