Upgrading Award Bios

I’m upgrading an older PII/PIII 366Mhz PC for a friend. I’m trying to upgrade their hard drive to a 40 GB, But the bios is too old. The bios string on the pc is as follows;i440bx/zx-w97-2a69ksnhc-00. My research indicates motherboard is made by Soltek. I have the latest Award flashbios utility, but I need the file name. The pc is currently running Award v4.51. Any suggestions would be greatly appreciated. I’ve run into a brick wall.
