EDIT: The mobo has a 2.05 ROM, will this let me use a 6Gb HDD, or do I need newer system plus accelerator, etc, etc?
As mentioned, Amiga OS 1.0-3.1 does not support partitions larger than 2 GB and harddrives larger than 4 GB. You can use your 6 GB harddrive, but only up to 4 GB, consisting of two 2 GB partitions. The remaining 2 GB can not be used reliably. Beware: you can often create larger partitions with Amiga OS 1.0-3.1, but this will not work reliably!
If you want to use the remaining space on your harddrive, you should use a different filesystem (check out Aminet for this) or go to OS 3.5/3.9. When using OS 3.5/3.9 you need a newer kickstart, extra fastram, a turboboard and a cd-rom drive (the drive is only needed during installation).
My advice: use the the 6 GB drive. You'll most likely never fill it up anyway, even if you only use two 2 GB partitions...
