Troubleshooting Troubleshooting Troubleshooting Q: Where will I find the model number of the mainboard? A: There are two places where you can find the model number of the mainboard: 1. Somewhere between the PCI slots you shall find MS-xxxx or the marketing name like “K7T Turbo”. You can also find the version number beside it. 2. At the back cover of the user's manual. Q: What do you mean by PCB version 1? A: PCB is printed circuit board. Saying PCB version 1 is the same as saying motherboard version 1.
845 GM/GLM/GEM/PEM/GVM series M-ATX Mainboard A: We strongly recommend that you do NOT connect those described CPU fan directly to your motherboard, as it draws so much power, that it could damage it. Please use a 3-Pin to 4-Pin Cable that comes together with the fan. Q: Can I use more than 512MB memory on Win9x or WinME? A: No, you can’t. You can only use more than 512MB memory on Win2000 or WinXP. This is a Microsoft OS issue. Please check http://support/microsoft. com/support/kb/articles/Q108/0/79.
Troubleshooting 3. Bugs are found 4. Customer-specific request When we release a new BIOS, there's usually a release note attached which lists the reason for the release. Refer to this release note and decide for yourself if upgrading to the new BIOS will be worth it. A word of advice, though, do not upgrade to the new BIOS, unless you really have to. Q: How do I update the BIOS? A: Please refer to http://www.msi.com.tw/support/bios/note.htm for details.
845 GM/GLM/GEM/PEM/GVM series M-ATX Mainboard Q: After flashing the bios and rebooting the system, the screen went blank. A: For AMI BIOS Rename the desired AMI BIOS file to AMIBOOT.ROM and save it on a floppy disk. e.g. Rename A569MS23.ROM to AMIBOOT.ROM Insert this floppy disk in the floppy drive. Turn On the system and press and hold Ctrl-Home to force update. It will read the AMIBOOT.ROM file and recover the BIOS from the A drive.

For example, a modem chipset contains all the primary circuits for transmitting and receiving data; a PC chipset provides the electronic interfaces between all subsystems. Clock Cycle Clock cycle (or tick) is the smallest unit of time recognized by a device.
Glossary ECC Memory (Error Correcting Code Memory) A type of memory that contains special circuitry for testing the accuracy of data and correcting the errors on the fly. EEPROM Acronym for Electrically Erasable Programmable Read-Only Memory. An EEPROM is a special type of PROM that can be erased by exposing it to an electrical charge. Like other types of PROM, EEPROM retains its contents even when the power is turned off. Also like other types of ROM, EEPROM is not as fast as RAM.
845 GM/GLM/GEM/PEM/GVM series M-ATX Mainboard IDE (Integrated Drive Electronics) A type of disk-drive interface widely used to connect hard disks, CD-ROMs and tape drives to a PC, in which the controller electronics is integrated into the drive itself, eliminating the need for a separate adapter card. The IDE interface is known as the ATA (AT Attachment) specification.
Glossary LBA (Logical Block Addressing) Logical block addressing is a technique that allows a computer to address a hard disk larger than 528 megabytes. A logical block address is a 28-bit value that maps to a specific cylinder-head-sector address on the disk. 28 bits allows sufficient variation to specify addresses on a hard disk up to 8.4 gigabytes in data storage capacity.
845 GM/GLM/GEM/PEM/GVM series M-ATX Mainboard PS/2 Port A type of port developed by IBM for connecting a mouse or keyboard to a PC. The PS/2 port supports a mini DIN plug containing just 6 pins. Most modern PCs equipped with PS/2 ports so that the special port can be used by another device, such as a modem. RAID RAID (Redundant Array of Independent Disks; originally Redundant Array of Inexpensive Disks) is a way of storing the same data in different places (thus, redundantly) on multiple hard disks.
