Insert the "IBM Netfinity 5500 M20 POST/BIOS Flash Diskette" into drive A. 2. Start up or restart your IBM Netfinity 5500 M20 server. 3. The system will boot off of the diskette and present a window which allows you the option to flash various options. Choose "1 - Update POST/BIOS". Then choose the number for the language you wish to use during POST and in Setup. 4. After the images are loaded from diskette, you will be asked if you would like to move the current POST/BIOS image to the backup ROM location. If you select 'Y', the current code will be flashed in to the backup bank immediately. 5. After that selection completes, you will be asked if you would like to save the current code to a diskette. If you select 'Y', you need to have a formatted diskette already available. 6. After this completes the system will update the flash ROM with the new code. When this is complete you will be prompted to remove the diskette and hit return to reboot the system. 2.0 Version Changes ____________________ Version Changes ------- ------------------------ 1.02 New release - BIOS revision 2. - Updated ACPI support for Windows 2000 beta 3. - POP could be set to same as PAP. - Removed option for Virtual Wire Mode PIC mode. - Fix timing problem with hotplug controller. - Fix Chinese Windows NT 4.0 installation hang. - Word around for problem with cache on new Intel processors. ------- ------------------------ 1.01 New release - BIOS revision 1. - Updated ACPI support for Windows 2000 beta 3. - Fixed processor cache info reported by SMBIOS in a multi-processor configuration. - Added a menu option to allow the user to specify the amount of time to offset the Service Processor clock from the main system clock. - Fixed a potential hang when POST 185 error code is issued. ------- ------------------------ 1.00 First release. 3.0 Trademarks and Notices ___________________________ THIS DOCUMENT IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
