what is the HDD capacity of abit BH6 MB?

I intend to expand my HDD up to 60G with my out of date abit BH6 Mother Board, but not sure what is the HDD capacity of abit BH6 MB?
I checked the BIOS info by using BIOS Wizard and it faild on Enhanced Disk Drive Specification & SMBIOS (DMI) Tests. Is there any solution except using an ATA PCI Adaptor?
Thanks in advance
