depends on your system. you can try enabling lba addressing in the BIOS. but easiest solution may be to buy a controller board that will recognise it. check out promise controllers at buy.com. give us the model number of your new drive and model of your computer

Sorry but i don't understand your question.

When you install a HD onto a MB then it will ask in the BIOS to set HD size.
Set to Automatically pick up the size of the new disk.
Are you saying you have an OS that is not picking up the HD size or that your BIOS isn't picking it up.

There are a number of variables here:

The age of your motherboard.

Size of the new hard drive.

Version of Windows.

For most older motherboards, you have 2 options if the motherboard does not recognize the full capacity of your hard drive:

1. Download and use the setup utility from the hard drive manufacture.
What these do is they install Drive / BIOS overlay software that tricks the BIOS into using the full capacity of the drive.
The Drive overlay is installed on the master boot record of the boot drive (C:) so, if you plan to use the new drive as the primary master, set it up that way before running the utility.

2. Install a PCI IDE controller card. This is really the best solution for an older motherboard. Not only does the controller detect the full capacity of your drive, but it will allow you to use the faster data transfer rate of new ATA 100 and ATA 133 hard drives.
Perhaps one of the most cost effective upgrades for under $30 (US)

If you are VERY lucky, the motherboard manufacture may have a BIOS update that increases the size of hard drives that the BIOS can recognize.
DON'T flash your BIOS unless the update corrects a specific problem that you are having.

Next, comes the Windows limitations.
The version of fdisk that ships with Windows 98 has a limit of 64GB.
The new version of fdisk for W98 can deal with drives up to 137GB.


Above 137GB, you will need to follow the drive manufactures instructions for how to setup the drive under W98.

Another thing you may run into is drive size spec-manship.
Most hard drive manufactures rate drive size in decimal form. 1KB = 1000 bytes.
Windows uses Binary form where 1KB = 1024 bytes.
So, in Windows your drive will appear around 3 percent smaller than advertised.
