you'll either have to make multiple 3GB partitions on it
This is not entirely true. You can make the partitions as big as you like. However, you cannot use more than 4GB
of the drive.
So make one 500MB system partition and one 3.4GB work partition and leave the rest empty, then it will run without problems.
To address the remaining parts (2GB in your case), you need additional software. You need a replacement IDE driver and a replacement file system.
So if someone suggests SFS or PFS3 as a solution, this is only half the truth, you need IDEfix or OS3.5/3.9, too.
