Intel Aurora (performance/AU) error...

[Demon-Xanth]

I recently aquired a PPro setup w/ an intel Aurora motherboard (450KX chipset) and get the following error on bootup:

NVRAM Checksum Error, NVRAM Cleared
NVRAM Data Invalid, NVRAM Cleared


Pressing esc to boot seems to work, however I would like to find out what causes it (and if it's associated to very sluggish performance)


Any ideas?

Ahh, the legendary Pentium Pro. I still have one myself. Had it running since end of 1995, and it still performs just as well as, if not better then, my wifes new celeron setup.

NVRAM = Non-Volatile RAM, where all configurable BIOS settings are stored.

That message is saying that the stored settings were corrupted, and set back to their defaults.

The same thing happened to a motherboard I bought from someone else. I'm not exactly sure of the cause; mine may have been because I used a different CPU than what was originally used on the board.

The only reason it would cause sluggish (as in non-optimal) performance is due to conservative settings used by the motherboard manufacturer. If you reconfigure the settings to their optimal settings (this may take time), everything should work great, performance-wise. Running NT or Linux will help with performance also.

You might want to replace the CMOS battery. In the case of many PPro boards, a dead CMOS battery means that you will lose all the performance settings in the motherboard, resulting in extremely sluggish performance. Usually stuff like all the caches have been disabled, and other P6 architecture stuff as well.
