Phoenix
Phoenix BIOS beep codes are a series of beeps separated by a pause, for example:
beep --- beep beep --- beep --- beep beep would be 1-2-1-2
- 1-1-4-1 - Cache Error (level 2)
- 1-2-2-3 - BIOS ROM Checksum
- 1-3-1-1 - DRAM Refresh Test
- 1-3-1-3 - Keyboard controller
test
- 1-3-4-1 - RAM Failure on address
line xxxx (check memory)
- 1-3-4-3 - RAM Failure on data
bits xxxx of low byte of memory bus
- 1-4-1-1 - RAM Failure on data
bits xxxx of high byte of memory bus
- 2-1-2-3 - ROM copyright notice
- 2-2-3-1 - Test for unexpected
