- Here is a little further information on the problem. We have tried adding
- wait states to memory and also slowing down the motherboard clock speed
- to no avail. Several people had mentioned that the "EEEEE"'s were documented
- in the SCO manuals, so I spent a few hours looking and found 1 reference
- to them, in the SCO Xenix Installation Guide. It mentions to verify diskette,
- and the N1 will boot on another system, making sure the diskette is inserted
- correctly (It has not been that bad a day, yet..), Verify that the door
- is completely closed, and it is; it also mentions to tap the edge of the
- floppy ??
- It concludes that is error messages EEEE still persists, call your provider
- to get a new floppy. We have replaced the floppy, and the ide controller.
-
- A 2nd machine was getting the same errors when booting from floppy (EEEEEE)
- and if you were persistent and kept trying it would eventually work, booting
- from the HD has been without a failure (2 days now). It was just booting
- from the floppy that gave problems.
-
- Several people have mentioned that AMI/BIOS should work fine. It is using
- the Symphony chipset. Both are 486's. (33 & 50). Not DX2's.
