Bob help! We are in Warren MI and need Ms-DOS help. Errors we are experiencing. The failed hard drive was cloned but new identical drives not working. General failure reading drive C. General failure reading drive CORY (what is CORY)? Bad or missing C:\DOS\HIMEM.SYS Error in CONFIG.SYS line 1 HMA not available: Loading DOS low C:\>mode mono Then nothing. Maybe the 2 clones weren't done correctly?
