Pyromaniac PRM: OwnerBanner (system banner)

Introduction

Under earlier versions of RISC OS, the Kernel would display a banner during start up. To allow customisation, this banner was moved to a new module, OwnerBanner.

The OwnerBanner's purpose is to announce the system information when the system boots, and present owner information when the desktop is entered.

Technical details

The OwnerBanner module listens for two services:

Service_DesktopWelcome: Displays a notice about the owner of the machine.
Service_OSInitBanner: Displays the OS startup banner, amount of memory, hardware being used and the owner information.

The owner information is read from the ROM using SWI OS_ReadSysInfo 9.

RISCOS Ltd4.10

The OwnerBanner module was first supplied with RISC OS 4.10, used for personalised masked and flash ROMs. The start up banner will display the system information, and the user's name and address as burnt into the ROM if present. During desktop startup the user's name will be displayed.

RISC OS Pyromaniac7.43

The OwnerBanner module was first supplied with RISC OS Pyromaniac version 7.43. The start up banner will display the system information, and the user's name and address as burnt into the ROM if present, or configured through the 'rominformation' group. No sprites are displayed in this version, and the desktop banner is omitted.
