sorry for the error. 1st pri hd shud read as 6.8 gb

A BIOS capacity barrier is the computer's inability to recognize hard drive capacities larger than allowed by the hard-coded programming contained in its Read Only Memory (ROM) chip. For example, your system BIOS might be capable of understanding a hard drive capacity up to 32 Gigabytes. You install a 40 Gigabyte hard drive and try to auto-detect it. The system freezes (hangs) because it does not understand the capacity being reported by the drive. In simpler terms, the systems BIOS just can't count that high. BIOS capacity limitations are the reason for BIOS upgrades, cylinder limitation jumpers, PCI Ultra ATA adapters, and EZ-BIOS which is part of the MaxBlast Plus installation software.These items help work around the BIOS limitations, making it possible for you to use the full capacity of the drive. In the past there have been 6 BIOS capacity limitations.

1. Systems with BIOS dated prior to July of 1994(504 MB Limitation)
2. Systems with BIOS dated after July of 1994 (2.048 GB Limitation)
3. 4.2 GB Limitation
4. 8.4 GB Limitation
5. 32 GB Limitation
6. 137 GB Limitation Windows 98, 98SE, ME, NT4.0,Win 2K,also limited

update Bios or use the hard drive manufactures disk installer

Some older hard drives need to have an extra jumper to say you have a slave on the same channel, look for a chart on the drive which is Master.

Go into the Bios STANDARD CMOS SETUP and set all channels to Auto detect
or
Some Bios have a IDE HARD DISK DECTECTION section

Check the format of the new drive FAT File or NTFS
Use Fdisk number (4) Display partition information
