XCMOSRD/XCMOSWR - DOS Programs for Reading and Writing CMOS Data
Description:
XCMOSRD and XCMOSWR programs allow to read motherboard configuration CMOS data
to a binary file and write back motherboard configuration CMOS data from an
existing binary file with previously read data. Both programs also display
all read and written data on screen.
These programs able to work with 56 bytes, 112 bytes and 242 bytes CMOS size
hardware while many other existing CMOS programs often support only older 56
bytes and 112 bytes CMOS hardware.
Besides configuration CMOS data XCMOSRD also reads RTC data (date and time in
Real Time Clock hardware), which are actually first 14 bytes, however XCMOSWR
doesn't write RTC data back to hardware leaving date and time untouched.
Examples:
1. Read RTC/CMOS data, display data on screen, write data to cmos.bin file:
xcmosrd cmos.bin
2. Write CMOS data from cmos.bin file, display CMOS data on screen:
xcmoswr cmos.bin
3. Read RTC/CMOS data, display data on screen, don't write any file:
xcmosrd nul
