NO BOOTABLE FLOPPY DRIVE 0 INSTALLED | No bootable floppy drive was detected. |
| Possible solutions: 1) Power down the |
| system and check all appropriate |
| connections, cables, etc. 2) In |
| configurations where no floppy drive is |
| installed, run System Configuration Utility |
| and make sure the diskette drive |
| configuration item is set to "None". 3) |
| Replace the diskette drive if necessary. |
NO INTERRUPTS FROM TIMER 0 | The periodic timer interrupt is not |
| occurring. |
RAM PARITY ERROR AT LOCATION xxxx | A RAM parity error occurred at the |
| specified (hexadecimal) location. |
ROM AT xxxx (LENGTH YYYY) WITH | An illegal adapter ROM was located at the |
CHECKSUM (zz) | specified address. An external adapter |
| (such as a video card) may be causing a |
| conflict. |
TIME/DATE CORRUPT - RUN SCU | The time and date stored in the real time |
| clock have been corrupted, possibly by a |
| power loss. |
UNEXPECTED AMOUNT OF MEMORY - RUN SCU | The amount of memory detected by |
| POST does not match the amount |
| specified in CMOS RAM. |
CMOS RAM TEST FAILED | A walking built test of CMOS RAM |
| locations 0E (Hex) - 3F (Hex) failed. |
DMA CONTROLLER FAULTY | A sequential read/write of the transfer |
| count and transfer address registers within |
| the primary and secondary DMA |
| controllers failed. |
FAULTY DMA PAGE REGISTERS | A walking bit read/write of the 16 DMA |
| controller page registers starting at |
| location 80 Hex failed. |
FAULTY REFRESH CIRCUIT | A continuous read/write test of port 61h |
| found that bit 4 (Refresh Detect) failed to |
| toggle within an allotted amount of time. |
INTERRUPT CONTROLLER FAILED | A sequential read/write of various |
| Interrupt Controller registers failed. |
ROM CHECKSUM INCORRECT | A checksum of the ROM BIOS does not |
| match the byte value at F000:FFFF. |
