8.1Software Updating

The Model 250 software resides in Flash Memory and is updated via the projector's serial Port A. To perform an update, a disk containing the updated Boot Software (boot.hex) and/or System Software (zsys.hex) and a PC with Windows 3.1 (Windows 95/98 with Procomm Plus fax/modem software) is required to perform update.

Boot Manager Software and System Software are separate products. Each may be updated independently. The System Software will depend on a specific version of the Boot Manager. Refer to the System Software release bulletin for Boot Manager version dependencies.
