+ | |||
+ | Main features: | ||
+ | |||

+ | * Boot menu via <key>CTRL+CLOSED-APPLE+RESET</key> or <key>CTRL+OPTION+RESET</key>. | ||
+ | * Allows dropping into the monitor immediately. | ||
+ | * Allows clearing memory expansion card. | ||
+ | * Allows launching diagnostics. | ||
+ | * Allows selecting boot device. | ||
+ | * 4X: Allows booting external 5.25 drive if disk supports it. | ||
+ | * 4X: With battery-backed RAMdisk, can configure default boot option. | ||
+ | * 5X: Replaces accelerator firmware. | ||
+ | * <key>CTRL+ESC+RESET</key> toggles accelerator speed and persists across ordinary resets. | ||
+ | * <key>CTRL+TAB+RESET</key> brings up a menu that lets you set accelerator state and some option. | ||
+ | |||
+ | In development: | ||
+ | |||
+ | * 5X - default boot option configuration like 4X, enhanced to set default accelerator state as well. | ||
