Non-Acer products, prototype cards, or modified opti ons can give false errors and inval id system responses.
50 Chapter 4 System Check Procedures Power System Check If the system will power on, skip this sect ion. Refer to System External In spection. If the system will not power on, do the fol lowing: q Check if the power cable is properly connected to the system and AC source.
Chapter 4 51 Checkpoints A checkpoint is either a byte or word value output to I/O port 80h. The BIOS outputs checkpoint s throughout bootblock and Power-On Self T e st (POST) to indicate t he task the system is currently executing.
52 Chapter 4 Bootblock Recover y Code Checkpoints The Bootblock recovery code gets control when the BIOS determines that a BIOS recovery needs to occur because the user has forced the upda te or the BIOS checksum is corrupt . Refer to “BIOS Recovery” on p age 25 for more information about perfor ming a BIOS recovery .
Chapter 4 53 POST Code Checkpoints The POST code checkpoints are the largest set of checkpoints during the BIOS preboot process.
