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.

1.If the BIOS detects error 2C or 2E (base 512K RAM error), it displays an additional word-bitmap (xxxx) indicating the ad-
dress 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.
