I suggest that the folks who are concerned about the fact that one some machine only 639K is reported, should read the document of UNVIRUS 9. It is speicifically written there: - ------------------------ Beginning ------------------------------------------- Note: On some machines (e.g. PS/2, HP Vectra), IMMUNE (and CHKDSK) will report less memory than is nominally available. For example, on a PS/2 with 640K, IMMUNE will report only 639K even when no virus is present. This is due to an extended BIOS area. In order to be certain that the deficiency is not du e to a virus, perform IMMUNE immediately after booting from your original (write- protected) DOS diskette. If you find only 639K you know that the missing 1K is not due to a virus, and that 639 is the parameter which should be supplied to IMMUNE. - ------------------------ End ------------------------------------------------- I guess that IMMUNE uses address 0:413h to determine the amound of memory and that Scan uses a different way. That's why people were a bit confused here. Hope I helped someone.. - -Yuval +--------------------------------------------------------------------------+ | BitNet: NYYUVAL@WEIZMANN Domain: NYYUVAL@WEIZMANN.WEIZMANN.AC.IL | | InterNet: NYYUVAL%WEIZMANN.BITNET@CUNYVM.CUNY.EDU Voice: +972-8-474592 | +--------------------------------------------------------------------------+ | Snail mail address: Yuval Tal, P.O Box 1462, Rehovot, Israel | +--------------------------------------------------------------------------+ | "Always look on the bright side of life" *whistle* - Monty Python | +--------------------------------------------------------------------------+
