>Also...what is fatal error 681?

681 means that random memory is getting trashed -- there are several possible
causes:

1. Buggy software (especially the stuff you install in your system folder)
2. DMA incompatibilities (Transwarp? DMA SCSI? OctoRam? AE GS-RAM?)
3. Inadequate power supply (too many cards and an Apple supply)
4. bad RAM chips

What kind of ram card do you have?
