    GA-586S2 APPENDIX A: POST MESSAGE When the BIOS encounters an error that requires the user to correct something, either a beep code will sound or a message will be displayed in a box in the middle of the screen and the message PRESS F1 TO CONTINUE, CTRL-ALT-ESC OR DEL TO ENTER SETUP will be shown in the information box at the bottom.
  • Page 96 Appendix A: Post Message Ö DISKETTE DRIVES OR TYPES MISMATCH ERROR - RUN SETUP Type of diskette drive installed in the system is different from the CMOS definition. Run Setup to re-configure the drive type correctly. Ö DISPLAY SWITCH IS SET INCORRECTLY Display switch on the motherboard can be set to either monochrome or color.
  • Page 97 GA-586S2 Ö ERROR INITIALIZING HARD DISK CONTROLLER Cannot initialize controller. Make sure the cord is correctly and firmly installed in the bus. Be sure the correct hard drive type is selected in Setup. Also check to see if any jumper needs to be set correctly in the hard drive.
  • Page 98 Appendix A: Post Message Ö MEMORY SIZE HAS CHANGED SINCE LAST BOOT Memory has been added or removed since the last boot. In EISA mode use Configuration Utility to re-configure the memory configuration. In ISA mode enter Setup and enter the new memory size in the memory field.
  • Page 99 GA-586S2 Ö Should Have ISA Board But Not Found PLEASE RUN EISA CONFIGURATION UTILITY The board installed is not responding to the ID request, or no board ID has been found in the indicated slot. When this error appears, the system will boot in ISA mode, which allows you to run the EISA Configuration Utility.
