Not getting the entire size of Hard Drive (80gb)

Hi, I have a win2k system and recently bought a 80 gig HD (maxtor) however my system doesnt recognizes the entire 80 gigs, all i can get is 31.4 gigs,I looked into the notes of the hard drive manual and it says some older BIOS maynot recognize more then 32gigs,
I have never done a BIOS Upgrade and read that it can be dangerous as it could make the entire system unusable if not done correctly
I have a American megatrend (AMI) Intel 450 mgz p3 processor
Is there any utility which helps identifying the entire 80 GIGS

Western Digital drives comes with a utility that you can put on the drive itself that provides a bios extension. Perhaps Maxtor has something similar.

I've use WD's utility with large drives and W2K without any problems.

The user manula which came along with the software says that if you have a system bios date oklde rthen 1995 you might want to upgrade the BIOS.
There is a utility which came along with the S/W but it didnt work much..I would try going through it again.
Any help on BIOS upgrade would be great!!

Thanks

you have to make sure you absolutly have the right bios for your motherboard, if the machine is a name brand like compaq, HP, Dell, IBM,...ect go to thier web site and look up the model/serial number of your computer, then get the bios for your machine, you may also need a installer flash utility, once you have the bios and the utility, you will need to make a boot disk on floppy by going to my computer then right click the floppy drive, select create a ms dos startup disk, once it is made copy the bios information file, has to be extracted if it is zipped, and the utility, write down the exact name of the utility so when you restart with the boot floppy and the dos prompt appears, type in the name of that utility, form there on it will ask or tell you what to do, after the bios is flashed and it tells you to restart, go into the bios and load setup default, then restart. you can set everything back after you reboot again, sometimes this is has to be done, sometimes they dont, but do it to make sure it starts back up ok. you can set everything the way you like it as soon as you see if it boots.
