Phoenix BIOS beep codes are a series of beeps separated by a pause, example:
beep --- beep beep --- beep --- beep beep would be 1-2-1-2

Basic Chart

• 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 interrupts
