Aopen's site states that BIOS v1.07 can support HDD > 33GB but not > 137GB, so I suspect its somewhere in between. The current BIOS is v1.15 so there have been a few updates since 1.07.
I see there are a few identical messages posted to Aopen's Forums within the last couple days, I presume that is you?
Anyway, I would go ahead and buy the drive, there is a very good chance it will support the full 60GB. 60GB HDD have been available for quite a long time now and at least two BIOS updates have been released during that time. They don't mention HDD support but tech some times fails to mention every feature or change of a new BIOS version.
On Edit - If it fails to detect the entire capacity, you have a few choices:
- Buy a cheap ATA/IDE PCI controller card with BIOS for $20 - $25, which would offer the benefit of using the drive in a 'faster' mode than UDMA/33.
- Use the 'alternate capacity' jumper on the drive if it is available, which would limit the drive to 33GB.
- Use a drive overlay utility such as Maxblast
