<pre><b>INT 81 - AMI WinBIOS - SECOND HARD DRIVE AUTODETECTION</b>

Notes:	used by WinBIOS with core version of July 1994 or later
	QEMM 7.5 began using this interrupt internally after the QPAT3
	  maintenance release when searching for "ROM holes", causing a
	  lengthy delay during bootup.	Adding the QEMM parameter RH:N will
	  avoid the QEMM call to INT 81 and speed up the boot process
