can check for modifications on your network drives. If 
you defined this type of access for a drive, your 
Kaspersky Inspector will be not able to check for stealth 
viruses and to check boot sectors and bad clusters on 
this drive. 
 Int 25h — enables Kaspersky Inspector to access objects 
using the disk drivers (INT 25h). In this case the 
program bypasses DOS and reads the disk sectors 
directly, i.e. via the 25h interruption (disk absolute 
reading). This mode can be used when checking for 
modifications on drives compressed using such 
programs as Stacker ver. 4.x or DriveSpace. The 
compression programs described above are supported 
by Kaspersky Inspector. Besides such disks are 
displayed using special icons. If you use other 
compression programs, that are not supported by 
Kaspersky Inspector, you must define the access mode 
to the compressed disk as INT 25h. 
 Int 13h — enables Kaspersky Inspector to access objects 
using INT 13h. In this case the program reads the disk 
directly via BIOS (the 13h interruption). You can use 
this mode when checking for modifications on the 
physical drives only, i.e. in partitions of a fixed disk. 
 IOS — enables Kaspersky Inspector to access objects using 
IOS (IO Supervisor). In this case the access type is 
determined by the following rules: if the 32-bit access to 
disk (VFAT ("Dragon") drives) is used or the protected-
mode disk compression software is running 
(DriveSpace) or the access to disk is implemented via 
Real Mode Mapper, the program calls the 32bit disk 
access driver (IOS) directly. Otherwise the program 
accesses the disk via INT 13h or the disk driver. In 
other words, in almost all the cases Kaspersky 
Inspector will access the drive via IO Supervisor. This 
option is available in Windows 9x only.
