- This is in the FAQ. While there -are- viruses that reduce the memory
- size by 1 Kb, they are not widespread, so it is rather unlikely that
- you have a virus. Most resident viruses reduce the memory size by a
- larger amount of bytes - usually at least 2 Kb.
-
- Check your CMOS setup - maybe you have told it to allocate 1 Kb from
- the top of memory for its data area. Are you using a SCSI controller?
- Any kind of additional operating system, like Unix? Is MS-DOS loaded
- high? With what kind of memory manager? All these reasons can cause
- memory reduction...
