NORTON UTILITIES 5.0+ TSRs - INSTALLATION CHECK/STATUS REPORT

AX = FE00h
DI = 4E55h ("NU")
SI = TSR identifier (see #03140)

Return:
SI = TSR reply lowercase version of SI on entry (i.e. SI ORed with 2020h) execpt SMARTCAN v8.0, which returns SI=6673h ('fs') AH = status 00h installed but disabled internally 01h installed and enabled AL = installed product 00h NCACHE-x or DISKREET 01h SPEEDRV / FILESAVE / EP / DISKMON v6+ installed 02h NCACHE2 / SMARTCAN 45h DISKMON v5 installed BX = length of *.INI file (DISKMON and FILESAVE/EP/SMARTCAN only) (see #03141,#03142) CX = segment of resident portion FFFFh if completely loaded high (NCACHE) DI may be destroyed ---FILESAVE/EP--- DL = ??? (apparently always 00h) ---DISKMON--- DX = ??? (apparently always 1AE6h [v5] / 1B86h [v6] / 1C26h [v7])

Notes: The value returned in CX is incorrect for NCACHE 6.00. All Norton Caches install as SMARTAAR drivers like SMARTDRV v3. NCACHE2 and SPEEDRV both support the SMARTDRV v4+ installation check. To detect Diskreet NDisk drives use CDS/DPB (see INT 21/AH=52h)
