I just bought a ibm 600e and I also am experincing the same error codes #00301. I would like to know the answer too. I checked the keyboard and found not problem. I did get past this error for the time being. just reboot and when the error come up, 1) press contro/alt/delete together and just after you release 2) PRESS ENTER BUTTON. this bypassed the error for now. I am still trying to figure this problem out
