SUMMARY
It has been reported that a critical error on a floppy disk drive, such as error 71 &quot;Disk not ready,&quot; can change the system configuration on a Tandy 4000 that is running QuickBasic Version 4.50.

After a critical error occurs, the drive is unreadable by the program or the operating system. This error causes the message &quot;Invalid configuration, press F1 to reconfigure,&quot; to appear the next time the system is rebooted.

The customer reported (after checking with a Tandy source) that the problem is caused by pin 34 (ready disk connect) on the drive controller. Apparently, the Tandy system normally ignores this pin, but when QuickBasic gets the critical error, the status is changed. To correct the problem, open the circuit for pin 34.



STATUS
Microsoft has not confirmed this information.

Additional query words: QuickBas unconfirmed
