Using my own handler might introduce incompatibilities with the existing
handler. The intention of my loop is to cause no side effects at all and
to be independent of the interrupt mask. I think this solution ensures a
minimum of interdependencies with other software.

Thank you anyway. Emulating the SCSI chip including a SCSI drive is
probably rather complicated, but maybe somebody will do it sooner or later.

Take care
