My PC is not able to reboot. As I could not erase/overwrite my previous DOS, I had to upload another DOS and had to manually select the functioning DOS. Now, it comes up as checksum does not match the headersum and hence cannot log into my PC.
Could you kindly, let me know what could be done.
To clear the checksum, with the powercord removed, remove the small battery on the motherboard, then attempt to boot your computer up, of course it will not boot, now removed the powercord again and put the battery back in place.
