- ODD Only
- Storage mode only (HDD)
- Dual mode (ODD+HDD)
The ODD only mode is actually very useful. When booting from an ISO, the install program can 'see' the Flash memory as a hard disk and some install programs can get confused (e.g. Windows will refuse to install onto the hard disk as it thinks it has booted from a removable drive!) - if I set the Zalman to ODD only mode, I get no problems and the install proceeds correctly.
Perhaps, the IOSel menu could have an option to select ODD mode which is then reset to Dual mode when the power is removed.
