Hi again, Annoying problem here, maybe someone can shed some light..
When I boot XP from regular IDE drive: - Bios POST finishes - XP goes directly into the graphical part of booting All good.
Once the jumpers are correctly set and power is supplied this will then reset the BIOS on the system. The NVRAM will be cleared when the jumper is closed (use the jumper from the password bridge (PSWD)).
To properly clear; AC power must be applied (not necessarily turned on) to the system for about 10 seconds while the jumper is closed.
Note: This is applicable to both Desktop and some Portable systems.
Portable systems however will require a door on the bottom or perhaps keyboard removal to access the coin cell battery.
Pins 1-2 once shorted will clear NVRAM and reset all ESCD Settings This is another method that can be used to reset the BIOS on the system by simply removing the CMOS coin cell battery and then clearing power from the system.
This is commonly done if you cannot access the jumpers or if you are dealing with a laptop system.
It contains information about ISA Pn P devices is stored.
Hi heres the story im having all sorts of problems with a base unit I bought, its a duron 1.2ghz with a pc266 system board does that sound right?
Anyway when I put an os on it kept freezing when windows found my soundcard so I had to disable it and put in a pci soundcard when I rebooted my computer said checking for NVRAM and it went no further so I rang the bloke who sold it to me and he said to reset the bios so I did and no it says checking for NVRAM update ok and goes no further...
The BIOS interface is designed for advanced users, you can change a setting that could prevent your computer from starting correctly and you could suffer a potential loss of data.
When the ESCD contained in the NVRAM needs to be cleared, this can be accomplished by manipulating the RTCRST (Real Time Clock Reset) jumper on the system board.
