To see the other 32GB of the drive, you have the following options:
1. Purchase OS3.5 or, preferably, OS3.9. You will need a CDROM drive to install either of these though.
2. Purchase a 4xEIDE'99 adapter and software from ELBox, which installs a driver/patch to enable full use of the drive. The adapter is easy to install, and cheap.
3. Get a copy of IDEFix97. Demo available on Aminet...but registration no longer available. Again, this installs a driver/patch to enable full use of your drive.
Good Luck.
