Mesg. Invalid system disk

[bonz_dragon]

I've run into a problem when I tried to add a slave drive into an old Pentium system running Win95. The slave drive would not detect as a slave but when I tried it as a Single Master it would spin up and show WD 2850 then error mesg. Invalid System Disk. Replace disk then press any key.
Now I can't get the original disk to load either w/o the same mesg. Can't get into BIOS either as it asks for CURRENT PASSWORD but there is none to enter!
Any suggestions?

Find the CLEAR CMOS jumper and use it. Remove the battery if it has one that can be removed. That will clear the password.

The drive had no system on it. There's one answer. The BIOS was probably set to manual for one IDE drive - hence the slave would not show. When you put the other drive in, the manually entered parameters didn't match, so the disk was rejected.

You must get into BIOS and set the drive parameters for both drives. You can enter them directly or use the recognition feature in BIOS.

Cleared CMOS and got back into BIOS, set IDE to Auto detect. Reinstalled original HD which was working and still get same error mesg. Invalid System disk Replace disk then press any key to continue.
What did I do wrong? Did I screw it up or is this still repairable?

Did you screw it up? I doubt it. I guess it has data on it. Can you try it in another PC?

:) Yeah , I have a K6-3 system I can try it in. Right now it has an ATA66 drive, will it be backwards compatable with a EIDE drive or is there a way to run both at the same time?
What's the best way to proceed w/o smokin something in the other system?
