Upgrading / Recovering the BIOS This chapter describes how to upgrade the BIOS and how to recover the BIOS if an upgrade fails. Preparing for the Upgrade Before you upgrade the BIOS, prepare for the upgrade by recording the current BIOS settings and obtaining the upgrade utility. Obtaining the Upgrade Utility You can upgrade to a new version of the BIOS using the new BIOS files and the BIOS upgrade utility, iFLASH.EXE. You can obtain the BIOS upgrade file and the iFLASH.EXE utility through Viglen’s World Wide Web site: http://www.viglen.com.

NOTE: Please review the instructions distributed with the upgrade utility before attempting a BIOS upgrade. This upgrade utility allows you to:

•= Upgrade the BIOS in flash memory. •= Update the language section of the BIOS.

The following steps explain how to upgrade the BIOS. Please follow all the step’s accurately.

Recording the Current BIOS Settings

1. As the computer boots, write down the BIOS identifier (version number) so a check can be made later to make sure the upgrade was successful.

2. Boot the computer and press <F2> when you see the message: Press <F2> Key if you want to run SETUP

3. Write down the current settings in the BIOS Setup program.

NOTE: Do not skip step 3. You will need these settings to configure your computer at the end of the procedure.

65

Creating a Bootable Floppy Diskette

1. Use a DOS or Windows 95/98 system to create the floppy disk. 2. Place an unformatted floppy diskette in the floppy drive and format the

floppy using the /S option. example: "Format a: /s" 3. Alternatively, place a formatted floppy in the floppy drive and use the "sys"

command. example: "sys a:" 4. Press <Enter>

Creating the BIOS Upgrade Floppy Diskette The BIOS upgrade file is a compressed self-extracting archive that contains the files you need to upgrade the BIOS.

1. Copy the BIOS upgrade file to a temporary directory on your hard disk. 2. From the C:\ prompt, change to the temporary directory. 3. To extract the file, type the name of the BIOS upgrade file, for example:

BIOS_10.EXE and press <Enter> or double click on the icon with the mouse in Windows NT.

4. Read the LICENSE.TXT file, which contains the software license agreement and the README.TXT file, which contains the instructions for the BIOS upgrade.

5. Insert the bootable floppy disk into drive A. 6. Copy the extracted files to the floppy disk. 7. The floppy disk now holds the BIOS upgrade and recovery files.

Upgrading the BIOS

1. Boot the computer with the floppy disk in drive A. The BIOS upgrade utility screen appears.

2. Select Update Flash Memory from a File. 3. Select Update System BIOS. Press <Enter>. 4. Use the arrow keys to select the correct .bio (Should only be one) file.

Press <Enter>. 5. When the utility asks for confirmation that you want to flash the new BIOS

into memory, select Continue with Programming. Press <Enter>. 6. When the utility displays the message upgrade is complete, remove the

floppy disk. Press <Enter>. 7. As the computer boots, check the BIOS identifier (version number) to make

sure the upgrade was successful. 8. To enter the Setup program, press <F2> when you see the message:

Press <F2> Key if you want to run SETUP 9. For proper operation, load the Setup program defaults. To load the

defaults, press <F9>. 10. To accept the defaults, press <Enter>.

66

11. Set the options in the Setup program to the settings you wrote down before the BIOS upgrade.

12. To save the settings, press <F10>. 13. To accept the settings, press <Enter>. 14. Turn off the computer and reboot.

Recovering the BIOS It is unlikely that anything will interrupt the BIOS upgrade, however if an interruption occurs, the BIOS could be damaged. The following steps explain how to recover the BIOS if an upgrade fails. The following procedures use recovery mode for the Setup program.

NOTE: Because of the small amount of code available in the non-erasable boot block area, there is no video support. You will not see anything on the screen during the procedure. Monitor the procedure by listening to the speaker and looking at the floppy drive LED.

1. Turn off all peripheral devices connected to the computer. Turn off the computer.

2. Remove the computer cover. 3. Locate the configuration header J2J1 and the third set of jumper pins 9-11. 4. On the header (J2J1), remove the jumper from pins 9-10 and replace on

pins 10-11 as shown below to set BIOS recovery mode for Setup.

Figure 10 5. Insert the bootable BIOS upgrade floppy disk into floppy drive A. 6. Replace the cover, turn on the computer, and allow it to boot. 7. The recovery process will take a few minutes. 8. Listen to the speaker.

•= Two beeps and the end of activity in drive A indicate successful BIOS recovery.

•= A series of continuous beeps indicates failed BIOS recovery.

9. If recovery fails, return to step 1 and repeat the recovery process. 10. If recovery is successful, turn off the computer and disconnect the AC

power cord from the computer. Remove the computer cover and continue with the following steps.

11. On the header (J2J1), move the jumper back to pins 9 -10 as shown below to set normal mode for Setup.

Chapter 5: Technical Information Note: This chapter is indented for experienced users only, and only to be used as a reference. Changes to or modify any of the components/ connectors listed herein can and will seriously damage your system, including the motherboard, CPU and/or any other hardware. SCSI Controller The embedded Adaptec AIC-7896 dual function SCSI controller provides both Ultra2 (LVDS) wide and Ultra wide SCSI interfaces as two independent PCI functions. PCI slot 4 is RAID-upgradeable, providing additional support for the ARO1130U2 RAIDport III controller by Adaptec. The SCSI bus is terminated on the server board with active terminators that cannot be disabled. The onboard device must always be at one end of the bus. The device at the end of the cable must be terminated. LVDS devices generally do not have termination capabilities. Non-LVDS devices generally are terminated through a jumper or resistor pack. The SCSI cable (Intel Part Number 745854-003) included with your server board (or integrator’s kit) has been modified to include active termination. The cable is capable of supporting both Ultra-2 and non-Ultra-2 SCSI devices. Proper termination of the SCSI bus is required for stable operation of SCSI devices. When attaching any SCSI device to the cable, verify that they are not terminated. This is usually a configurable option using a jumper or terminator block on the device. Check the documentation that came with your SCSI device to verify this option. Termination of the SCSI bus is implemented using the active termination on the server board along with the active termination at the end of the SCSI cable. IDE Controller IDE is a 16 bit interface for intelligent disk drives with disk controller electronics onboard. The PCI/ISA/IDE Accelerator, also known as PIIX4e, is a multifunction device on the server board that acts as a PCI based Fast IDE controller. The device controls:

•= PIO and IDE DMA/bus master operations •= Mode 4 timings •= Transfer rates up to 33 MB/s •= Buffering for PCI/IDE burst transfers •= Master/slave IDE mode •= Up to two devices per channel; two channels, IDE0 and IDE1

NOTE 18 inch maximum length of IDE cable on each channel: You can connect an IDE signal cable, up to a maximum of 18 inches each, to each IDE connector on the server board. Each cable can support two devices, one at the end of the cable and one 6 inches from the end of the cable.

Operating Systems and IDE hard drives Standard CHS is the translation that has been used for years. Its use limits IDE capacity to maximum of 528MB regardless of the size of the drive used. Logical Block mode overcomes the 528MB maximum size limitation imposed by the Standard CHS mode. It should be used only when the drive supports LBA (Logical Block Addressing), and the OS supports LBA, or uses the BIOS to access the disk. Extended CHS mode also overcomes the 528MB maximum size limitation imposed by Standard CHS mode. It can be used with drives, which are larger than 528MB that do not support LBA. Auto Detected allows the BIOS to examine the drive and determine the optimal mode. The first choice is to utilise Logical Block mode if it is supported by the drive. The second choice is to utilise Extended CHS mode if the drive topology allows. If neither of the above methods is possible, the Standard CHS mode is used. Different operating systems have different abilities regarding IDE translation mode. UNIX operating systems (as currently implemented) do not support either LBA or ECHS and must utilise the standard CHS method. UNIX can support drives larger than 528MB, but does so in its own way. OS/2 2.1 and OS/2 Warp can support LBA, ECHS or standard CHS methods. Note that LBA support may require a switch setting on an OS/2 driver in order to operate in that mode. OS/2 2.0 & Novel NetWare can support either ECHS or standard CHS methods. In order to use LBA with NetWare a driver that supports current parameters must be used. OS/2 2.0 does not support LBA. DOS & Windows can use LBA, ECHS or standard CHS methods. The '32-bit Disk Access' driver built into Windows WDCTRL.386 can only be used with the standard CHS method, to use either LBA or ECHS method and '32-bit Disk Access' an alternative .386 driver must be installed; this combination will also provide the best performance. If this driver is not installed and the drive fitted to the system supports Type F DMA on the ISA interface or Mode 3 on the PCI interface then higher performance will be achieved by NOT using '32-bit Disk Access'.

Network Controller The server board includes a 10BASE-T/100BASE-TX network solution based on the Intel 82559 single chip Fast Ethernet PCI Bus Controller. As a PCI bus master, the controller can burst data at up to 132 MB/s. The controller contains two receive and transmit FIFO buffers that prevent data overruns or underruns while waiting for access to the PCI bus. The controller has the following:

•= 32 bit PCI bus master interface (direct drive of bus), compatible with PCI Bus Specification, Revision 2.1

•= Chained memory structure with improved dynamic transmit chaining for enhanced performance

•= Programmable transmit threshold for improved bus utilization •= Early receive interrupt for concurrent processing of receive data •= Onchip counters for network management •= Autodetect and autoswitching for 10 or 100 Mbps network speeds •= Support for both 10 Mbps and 100 Mbps networks, capable of full or half

duplex, with back-to-back transmit at 100 Mbps

The network status LEDs on the server board indicate:

•= Transmit/receive activity on the LAN •= Valid link to the LAN •= 10/100 Mbps transfer mode

Video The onboard, integrated Cirrus Logic CL-GD5480 64 bit VGA chip contains an SVGA controller that is fully compatible with these video standards: CGA, EGA, Hercules Graphics, MDA, and VGA. The standard configuration comes with 2 MB of 10 ns onboard Synchronous Graphics Memory (SGRAM). The video controller supports pixel resolutions of up to 1600 x 1200 and up to 16.7 Million colors. The SVGA controller supports analog VGA monitors (single and multiple frequency, interlaced and non-interlaced) with a maximum vertical retrace non-interlaced frequency of 100 Hz. You cannot add video memory to the server board. Depending on the environment, the controller displays up to 16.7 M colors in some video resolutions. It also provides hardware accelerated bit block transfers (BITBLT) of data.
