Beep Codes - HP Vectra VLi8 Technical Reference Manual

Beep Codes

If a terminal error occurs during POST, the system issues a beep code before
attempting to display the error in the upper left corner of the screen. Beep
codes are useful for identifying the error when the system is unable to display
the error message.

modules should be used.

If the BIOS detects error 2C or 2E (base 512K RAM error), it displays
an additional word-bitmap (xxxx) indicating the address line or bits that
failed. For example, "2C 0002" means address line 1 (bit one set) has
failed. "2E 1020" means data bits 12 and 5 (bits 12 and 5 set) have failed
in the lower 16 bits.
