Error Messages The following tables describes the error messages that may appear during POST. Each message is listed with a detailed description of the error. Memory Message Displayed Gate20 Error Multi-Bit ECC Error Parity Error RAM R/W test failed CMOS Memory Size Wrong Description The BIOS is unable to properly control the motherboard's Gate A20 function, which controls access of memory over 1 MB. This may indicate a problem with the motherboard. This message will only occur on systems using ECC enabled memory modules. ECC memory has the ability to correct single-bit errors that may occur from faulty memory modules. A multiple bit corruption of memory has occurred, and the ECC memory algorithm cannot correct it. This may indicate a defective memory module. Fatal Memory Parity Error. System halts after displaying this message. This message is displayed by the AMIBIOS8 when the RAM read/write test fails. The base memory (memory below 1MB) size that is reported in the CMOS (offset 15h) mismatches with the actual size detected. This condition may occur when the hole is set at 512K base memory or when CMOS is corrupted. Boot Message Displayed Boot Failure ... Invalid Boot Diskette Drive Not Ready A: Drive Error B: Drive Error Insert BOOT diskette in A: NO ROM BASIC Description This is a generic message indicating the BIOS could not boot from a particular device. This message is usually followed by other information concerning the device. A diskette was found in the drive, but it is not configured as a bootable diskette. The BIOS was unable to access the drive because it indicated it was not ready for data transfer. This is often reported by drives when no media is present. The BIOS attempted to configure the A: drive during POST, but was unable to properly configure the device. This may be due to a bad cable or faulty diskette drive. The BIOS attempted to configure the B: drive during POST, but was unable to properly configure the device. This may be due to a bad cable or faulty diskette drive. The BIOS attempted to boot from the A: drive, but could not find a proper boot diskette. Reboot and Select proper Boot device or Insert Boot Media in selected Boot device BIOS could not find a bootable device in the system and/or removable media drive does not contain media. This message occurs on some systems when no bootable device can be detected. 60 Chapter 4
