My PC is a Compaq Presario (don't laugh) equipped with 64 MB when I bought it. This was an upgrade to 196 MB and the chip, Micromemory SDRAM PC100, are supposed to be compliant to the Compaq standard so they should be compatible, both the chip and the mainboard.
The BIOS of a Compaq is utter crap, I can't configure anything more than the monitor and such things so...
Everything boots fine though, windows reports the correct amount of memory and I haven't ran into any problems. Everything runs alot faster now.
The only thing that worries me is that if there's a possibility that this error means that I won't get 100% out of the upgrade.
Sounds like the mem is working a treat, you may want to use some mem checking software, just to make sure its up to scratch
In which case the "error " prompt sounds like a compaq/bios problem, though it probably isnt a problem really.
I have had a few bad experiences with compaq machines, (particularly pre 1998 jobs), and like you say they dont exactly make things easy for you....but you may want to scour the compaq support sites if you think this will help! (it didnt help me!)
Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
