On the software side:
A DVD file system like AllegroCDFS or a Cd-rom one that supports "overburned Cd-roms", like CacheCDFS (It comes both on AmigaOS 3.9 and the IDEFix97 package).
Of course, you will need the software driver of your particular IDE interface (Tandem IDE) to be correctly installed.
On the hardware side:
An IDE/PATA DVD unit (SATA wont do unless you use an adapter)
Good luck!
PS: Remember to have properly adjusted your CD0 device in /devs/dosdrivers to reflect your unit number and your device name.
