If the BIOS only permits a maximum size of 512 Mb then the BIOS is so old it does not support disks larger than 512 Mb.

You probably need overlay software to support the hard disk.  Try

Or rather

You could try the Motherboard manufacturer's web site and see if there is a BIOS upgrade.

If this 486 is new enough to have PCI slots, you can always get a PCI hard drive controller.  Then your 486 could use any size drive up to the newest 120GB ones.

Commented:
Most of the controllers I have seen lately require pentium processors.
For example:  http://www.maxtor.com/products/UltraATA100/UltraATA100.htm
 System Requirements:
Available PCI expansion slot
Pentium class or higher PC
Windows 98
Windows Millennium
Windows NT 4.x SP4 or higher
Windows 2000

Free hard drive overlay: http://www.uwm.edu/~aleinss/ezdrive.zip.  Unzip to a disk and run it from DOS.  Make sure to install EZ-BIOS.
