A600 mobo, possible to use?

I have a laptop HDD, it's actually 6Gb, is this too big for an A600?

Yes and no. Amiga OS 1.0-3.1 has a maximum drivesize of 4 GB and a maximum partitionsize of 2 GB with their built in filesystems. Larger partitions sometimes appear to work, but when the partitions starts to fill up, chances are files will get corrupted.

This means that in your case you can use a maximum of 4 GB of your harddrive (2x 2 GB) or you can use a different filesystem which support larger harddrives and partitions or you can use Amiga OS 3.5/3.9, which natively support larger drives and partitions. Amiga OS3.5/3.9 needs at least an 68020 with some fastram, and turboboards for the A600 are rather hard to find.

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...
