IOMD port status

Overview

At present the port consists of three components:

• A HAL targetting Acorn’s IOMD chipset and close relatives in the ARM7500 and ARM7500FE.
• The standard ‘HAL’ version of the RISC OS 5 kernel and the standard ROM modules
• Additional custom driver modules, e.g. Quadrature mouse, VIDC20Video as required

At present the port is known to be functional on the following hardware devices:

• Risc PC with ARM610, ARM710, or StrongARM SA-110
• Risc PC Kinetic with up to 256MB+256MB+2MB
• A7000 with an ARM7500
• A7000+ with an ARM7500FE
• Emulators for the above, such as RPCEmu

It is worth recalling that RISC OS 5 uses the processor in 32 bit mode, therefore

• There is no provision for mixing 26-bit mode and 32-bit mode applications on the same machine – legacy applications will first need updating
• If you have RISC OS Select, you would be losing any of RISCOS Ltd’s enhancements since RISC OS 4.02 that don’t have equivalents in RISC OS 5

The IOMD port has a stable version available to download, and can be purchased on ROM chips via the store. Users with an adequate backup strategy in place may wish to try softloading the new features present in the beta version instead.

Current status

The RISC OS Roadmap covers items which are not specific to the IOMD port, and the bug tracker covers defects in existing components. This table covers planned future tasks or areas that are yet to be implemented on IOMD.
