: I NEED HELP I INSTALLED A 40 gb HARDRIVE , BUT MY SYTEM ONLY READS IT AS BEING 31.4, I NEED A BIOS UPDATE. HOW DO I DO THIS?

Be VERY Careful. It is unbelievably easy to misflash your BIOS. If you misflash your BIOS your computer will not work until you recover your BIOS. Be sure that any "update" you find will support the features you need (for you, >32 GB HDD) by studying the BIOS release notes (tells what changes were made since the previous update).

1. Write your BIOS Identity string and your CMOS settings on paper before you start. You will need the ID string to get help if your efforts aren't successful. You must clear and reset CMOS settings after BIOS update - Visible and invisible CMOS settings get changed when you flash the BIOS. Find your mainboard maker, the model number and the revision number; all may be important (sometimes board makers use some different chipsets for different revision numbers).

2. Learn all you can about recovering corrupt BIOS (search the internet for BIOS Recovery, Corrupt BIOS, Boot Block Recovery and similar, with variations. You will get lots of information. If your BIOS update efforts are a disaster (unrecoverable mis-flash), remember: http://www.badflash.com

3. The BIOS file and flash utility are usually zipped files. The flash utility will work correctly ONLY when you boot with a DOS floppy. If you try to unzip these files with WinZip or other windows Unzipper you can easily start the flasher. The flasher won't run right under windows, but it will run just well enough to misflash your BIOS.

4. Find your BIOS update and the right flash utility at your mainboard maker's web site (internet search should find it if it is still active). Your BIOS update must match your mainboard maker, model and revision - and the flash utility must match the BIOS chip and the mainboard chipset.

5. The mainboard maker should have update instructions and possibly corrupt BIOS recovery instructions posted on the web site. Please read and understand them - post a new question if there is anything you are uncertain about.

6. Follow mainboard maker's flash directions (sometimes not easy to read or understand). When done, restart computer, enter CMOS settings and choose "optimal" or "default" (whichever is available), exit and save the settings. This will clear the flash trash out of the CMOS settinge. After you have the computer working again re-enter the settings you wrote down to begin with.

7. It is incredibly easy to mis-flash your BIOS. DO NOT interrupt the flash process after you start it - let it finish, otherwise you get a misflashed BIOS. Use a UPS if you can get one - a power blink will mis-flash your BIOS.

8. If in doubt about the quality of the BIOS update, find out what version BIOS you have (the release date, not the core date) and practice flashing with the version you have now. Keep a copy of it. When you are comfortable with the process flash with the update. If you have prepared well you will either have an updated BIOS or you will be able to put it back like it was to begin with. You'd be surprised how many can't go back after making a few "simple" changes. BIOS update is a major change.

Please be willing to share what you learn about BIOS updates with others on this Forum and wherever you find some asking for help.

If the BIOS update doesn't give you the feature(s) you need, post a new message. There are alternatives and work arounds to handle most problems, including auxiliary BIOS.

Good Luck,
Henry
