=> R0 = 0
R1 = host ID
Potential errors:
&00020100 - No room for SCSI driver workspace
&00020103 - SCSI bus failed to reset
&00020104 - Invalid SCSI host ID
This call resets all options set by SCSI_Control to their default
states and removes any device reservations. In addition it sets a new
host ID and causes a full reset of the SCSI bus by driving the SCSI bus
RESET line. If the SCSI card supports LED control (SCSI_Control2),
then the LED is switched off.
The default states set for each device are:
Reservation - none
Timeout - 250ms timeout
Error response - report check condition as an error
Queue behaviour - wait until slot becomes free
Disconnect - allow disconnect/reselect
Transfer - disable sync transfers
WideSCSI - disable WideSCSI
