CMOSSave CMOSRest CMOSChk restore corrupted CMOS from backup and check that CMOS has not been tampered with. Naive users sometimes meddle with CMOS settings. We need a fast way to put the scores of subtle CMOS configuration settings back the way they were. Power surges can corrupt CMOS. We need a way for a naive user to quickly restore all the CMOS settings. If the battery fails, the contents will be lost. We need a way to restore a known working CMOS configuration. CMOSRest restores ALL of CMOS, including the proprietary extended CMOS settings like wait states, clock speeds, shadow RAM etc. CMOSRest can also be used to toggle between two CMOS configurations, for example with and without a removable hard drive installed. CMOSChk can detect subtle corruption to CMOS, as might be caused by a rogue program or a virus, something that might slow your machine or make it unreliable. The CMOS suite will work under DOS, Windows 3.x, Windows 95/98/ME or OS/2. It partly works under NT, Windows 2000, XP, Vista and Windows 7. See cmossave.manual.html details. However, these utilities are intended to be used mainly within autoexec.bat during the DOS phase of the boot. Further, there will be spurious CMOS changes when you reboot between Win95 and NT. The suite can also be used to rapidly clone the same CMOS settings in many machines.
