ASUS CUV4X-CME User â s Manual 7 HARDW ARE SETUP Connectors H/W SETUP Internal Connectors 1) Primary (Blue) / Secondary IDE Connectors (40-1 pin IDE1/IDE2) These connectors support the provided UltraDMA/66 IDE hard disk ribbon cable. Connect the cable â s blue connector to the primary (recommended) or secondary IDE connector , then connect the gray connector to the UltraDMA/66 slave device (hard disk drive) and the black connector to the UltraDMA/66 master device. It is recommended that non-UltraDMA/66 devices be connected to the secondary IDE connector . If you install two hard disks, you must configure the second drive to Slave mode by setting its jumper accordingly . Refer to the hard disk documentation for the jumper settings. W ARNING! Some pins are used for connectors or power sources. These are clearly distinguished from jumpers in the Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard. IMPORT ANT : Always connect ribbon cables with the red stripe to Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on floppy disk drives.

The power LED on the front panel of the system case lights up. For A TX power supplies, the system LED lights up when you press the A TX power switch. If the monitor complies with â greenâ standards or if it has a power standby feature,the monitor LED may light up or switch between orange and green after the system LED does. The system then runs the power-on tests. While the tests are running, the BIOS beeps or additional messages appear on the screen. If you do not see anything within 30 seconds from the time you turn on the power , the system may have failed a power -on test. Check the jumper settings and connections or call your retailer for assistance.

For A TX power supplies, you can press the A TX power switch after exiting or shutting down the operating system. If you use W indows 9X, click the Start button, click Shut Down, then click Shut down the computer? The power supply should turn of f after W indows shuts down. NOTE: The message â Y ou can now safely turn of f your computer â does not appear when shutting dow n with A TX power supplies. Powering Up H/W SETUP
ASUS CUV4X-CME User â s Manual 13 HARDW ARE SETUP Connectors H/W SETUP Managing and Updating Y our BIOS Upon First Use of the Computer System It is recommended that you save a copy of the original motherboard BIOS along with a Flash Memory W riter utility (AFLASH.EXE) to a bootable floppy disk in case you need to reinstall the BIOS later . AFLASH.EXE is a Flash Memory W riter utility that updates the BIOS by uploading a new BIOS file to the programmable flash ROM on the motherboard. This file works only in DOS mode. T o determine the BIOS version of your motherboard, check the last four numbers of the code displayed on the upper left-hand corner of your screen during bootup. Lar ger numbers represent a newer BIOS file. 1. T ype FORMA T A:/S at the DOS prompt to create a bootable system disk. DO NOT copy AUT OEXEC.BA T and CONFIG.SYS to the disk. 2. T ype COPY D:\AFLASH\AFLASH.EXE A:\ (assuming D is your CD-ROM drive) to copy AFLASH.EXE to the boot disk you created. NOTE: AFLASH works only in DOS mode. It does not work in the DOS prompt within W indows and does not work with certain memory drivers that may be loaded when you boot from the hard drive. It is recommended that you reboot using a floppy disk. 3. Reboot the computer from the floppy disk. NOTE: BIOS setup must specify â Floppy â as the first item in the boot sequence. 4. In DOS mode, type A:\AFLASH <Enter> to run AFLASH. IMPORT ANT! If the word â unknownâ appears after Flash Memory:, the memory chip is either not programmable or is not supported by the ACPI BIOS and therefore, cannot be programmed by the Flash Memory W riter utility .

ASUS CUV4X-CME User â s Manual 15 HARDW ARE SETUP Connectors H/W SETUP Updating BIOS Procedures 1. Download an updated ASUS BIOS file from the Internet (WWW or FTP) (see ASUS CONT ACT INFORMA TION on page 3 for details) and save to the boot floppy disk you created earlier . 2. Boot from the floppy disk. 3. At the â A:\â prompt, type AFLASH and then press <Enter>. 4. At the Main Menu, type 2 then press <Enter>. The Update BIOS Including Boot Block and ESCD screen appears. 5. T ype the filename of your new BIOS and the path, for example, A:\XXX- XX.XXX , then press <Enter>. NOTE: T o cancel this operation, press <Enter>. 6. When prompted to confirm the BIOS update, press Y to start the update. W ARNING! Update the BIOS only if you have problems with the motherboard and you know that the new BIOS revision will solve your problems. Careless updating can result in your motherboard having more problems! Updating BIOS BIOS SETUP
16 ASUS CUV4X-CME User â s Manual HARDW ARE SETUP Connectors H/W SETUP 7. The utility starts to program the new BIOS information into the Flash ROM. The boot block is updated automatically only when necessary . This minimizes the possibilities of boot problems in case of update failures. When the programming is done, Flashed Successfully appears. 8. Follow the onscreen instructions to continue. W ARNING! If you encounter problems while updating the new BIOS, DO NOT turn off the system because this may cause boot problems. Just repeat the process, and if the problem still persists, load the original BIOS file you saved to the boot disk. If the Flash Memory Writer utility is not able to successfully update a complete BIOS file, the system may not boot. If this happens, call the ASUS service center for support.
