Intel® Entry Server Board SE7221BK1-E User Guide Troubleshooting BIOS Event Log The BIOS will output the current boot progress codes on the video screen. Progress codes are 32 bit quantities plus optional data. The 32 bit numbers include Class, Subclass and Operation information. Class and Subclass point to the type of the hardware that is being initialized, where as the Operation field represents the specific initialization activity. Based upon the data bit availability to display Progress Code, a progress code can be customized to fit the data width. The higher the data bit, higher the granularity of information, which could send on the progress port. The progress codes may be reported by the system BIOS or the option ROMs. The Response section in following table is divided in 3 different types Warning - The message is displayed on screen and error is logged in SEL.
