MCMaster Error Messages
The MCMaster Option ROM displays one of several error messages when it encounters a hardware problem. The ROM will display one of these error messages and halt the system to prevent data corruption.
MCMaster Error 01: DMA Set to greater than 16Meg
The DMA Controller on the PS/2 Motherboard is limited to 24 bits of addressing, imposing a 16 Megabyte limit on the address range in which DMA transfers can take place. If the system tries to do a DMA transfer beyond this range, data can be corrupted. If this error occurs, reconfigure the system, selecting one of the "<16M" memory options.
MCMaster Error 02: DMA Set for
This error occurs when memory regions that appear contiguous from the MCMaster's point of view are not contiguous from the bus's point of view. This is most likely to occur if you attempt to boot OS/2 with the memory option "Mapped, Report ALL" selected. To fix the problem, select "Report MCMaster" or "Unmapped."
MCMaster Error 03: Invalid Status
This message might indicate a hardware error on the MCMaster. If you see this error message, it will also display a group of numbers. Make a note of the numbers, and contact Kingston Technical Support.
MCMaster Error 04: Bus Timeout
This message indicates that an adapter on the Micro Channel bus is holding the bus too long, causing problems for the MCMaster. If you see this message, take note of what adapters are in the system and contact Kingston Technical Support at (714)
