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)
