AH = 18h BP = 0012h (driver ID for V_SYSTEM) AL = sense of test (00h equal, 02h non-equal) BX = AND mask DX = pattern SI = first vector address to search DI = offset in HP header of field to test
Return:
AH = status (00h,FEh) (see #03744 at INT 6F/AH=00h"HP Vectra") BP,DS destroyed ---if AH=00h--- SI = first matching vector address
Desc: Compare successive drivers' header fields starting at address SI until the header field AND BX is either equal or non-equal to DX
