NCR S26 manual Memory at 15 MB 16 MB, Operation of ECC

Advanced System Configuration

You must disable this parameter if you installed SIMMs without parity.

Operation of ECC

This parameter permits you to select the error detection mode. The ECC operation options follow:

∙None - detects single-bit errors and automatically corrects any error but does not set the single-bit error flag in the chipset. In this option, the operating system does not receive any signal even if there are system errors.

∙Single-bit- detects single-bit errors, automatically corrects any error, and sets the single-bit error flag in the chipset. The setting of the single-bit error flag is a signal to the operating system that ECC detected single-bit errors.

∙Multiple-bit- detects multiple-bit errors and sets the multiple-bit error flag in the chipset but does not correct the errors. The setting of the multiple-bit error flag is a signal to the operating system that ECC detected multiple-bit errors.

∙Both - detects both single- and multiple-bit errors but corrects only single- bit errors. This option sets both the single-and multiple-bit flags in the chipset to send signals to the operating system that ECC detected errors.

Memory at 15 MB - 16 MB

To prevent memory address conflicts between the system and expansion boards, reserve this memory range for the use of either the system or an expansion board. Before setting this parameter, check your add-on expansion board manual to determine if the board needs this memory space. If not, set this parameter to System Use.
