Ah, the return of the dreaded Supervisor password. If you want to continue to use the machine and hard drive DO NOT REPLACE THE SYSTEM BOARD! If you do the hard drive will never boot up again. In this case 'shell' means bare system (basically the system board in case). I have had a great deal of experience with those passwords on the machines. The Supervisor password is basically a combination of a Hard Drive password and a Power On password. If the shell has the same supervisor password as the hard drive, it will boot up seamlessly. If you go into E-Z Setup you will need the supervisor password to make any changes, but otherwise the system will work fine. If you move the hard drive into another machine, it will prompt you for a hard drive password, which is the supervisor password. If you put another hard drive in the shell, you will need the supervisor password, and then you will either have to clear it or add it to the new hard drive to continue. This ensures that the machines will never be broken up. If the system board is replaced the supervisor password will be removed from the shell, but not the hard drive. If the shell no longer has the supervisor password, when you boot up it will prompt you for a hard drive password. To date no one has cracked the hard drive passwords (alot of talk, but no one has _done_ it). In the case below, the supervisor password is not known, so the hard drive will be a paperweight if the system board loses the password. The supervisor password will allow you to get around the power on password of the machine. The idea is that the supervisor configures the system, and then gives it to the person. They put their own power-on password on, but the supervisor can always get into the system. Currently I know that the 755's, 750's, and 760's all have this functionality. I know that the 700's, 720's, and 360's do not. You cannot have a hard drive password and a supervisor password, as the supervisor password occupies the password 'location' on the hard drive. You will have to use a Power On password if you want to have a password, as the system has 'space' for both of those. Randall rjking@kodak.com rjking@servtech.com ps- going back to the holy grail of MWave, is there a FAQ on how to get it to work with DOS games? pps- I am getting locked up with my system when I pop in my IBM (!?!?) Ethernet card, and then use MWave stuff. It's goes for about 30 seconds, and then WHAMMO, the system locks. If I pop out the card it sometimes resumes. Anyone had this problem? ---------- From: owner-tp750 To: TP750 Subject: IBM 750CE PASSWORD Date: Thursday, February 29, 1996 5:18PM Help!!! We have an IBM 750ce laptop that we do not know the supervisor password. The orginal owner died. IBM tells us that we have to replace the motherboard and hard drive. We have already tried to disconnecting the internal batteries. Thanks James L. Peek jlpeek@ix.netcom.com
