============================================= Information for Phoenix BIOS on EKF CD3-JIVE: ============================================= Howtos, Tips and Hints: ----------------------- * How to reset CMOS when it is not possible to enter BIOS Setup: If the BIOS is configured in such a way, that it is not possible anymore to enter Setup (F2 key) and to reset CMOS (F9 key), there exist now two further options to completely reset CMOS to factory defaults: 1. CTL-ALT-F9 Press CTL-ALT-F9 during POST. Timeframe to do this: Keyboard LED 'NUM' goes on until boot starts. If no keyboard is available, or BIOS setup is in a state, that no keyboard is enabled, use the following option to reset CMOS: 2. Reset-in-Series option Step A: Restart board either by pressing reset button in front panel, by making a Power-Off-ON sequence, by pressing CTL-ALT-DEL or whatever ... Step B: Now press Reset-Button (*1) again during the timeframe when green LED 'GP' in front panel goes on (this is normally immediately after reset) and BEFORE this LED is switched off for the first time. Repeat step B exactly two (2) times (*2), i.e. step B must be executed three times in series after any reset. Now wait until the BIOS prompts you to enter Setup ... Note *1: Instead of pressing reset button, a Power-Off-ON sequence can be made similarly. It should be noted that this requires a full battery. Note *2: The counter, which is used for this option, is cleared when LED 'GP' goes off the first time during POST. If you want to reset CMOS and if reset button is pressed to late (i.e. LED GP is off again), restart with step 2A. With both options the BIOS loads - after next reset - factory defaults into CMOS. * How to reset ESCD when it is not possible to enter BIOS Setup: Press SHIFT-ALT-F9 during POST. The allowed timeframe for this: keyboard LED 'NUM' goes on until boot starts. The system restarts immediately after SHIFT-ALT-F9 and ESCD (Extended System Configuration Data) will be reset. * The fastest boottime is achieved by selecting the following Setup options: Setup (F2) -> Advanced -> ATA/IDE Configuration -> Hard Disk Pre-Delay -> Disabled Setup (F2) -> Advanced -> BIOS/POST Options -> Summary Screen -> Disabled * Win2k cannot be installed from an USB2.0 device (e.g. CDROM) if boot from USB2.0 is enabled in BIOS setup. This is a problem of Win2k. To allow installation of such a device set BIOS option -> Setup (F2) -> Advanced -> USB Configuration -> 'Boot from USB 2.0 Devs in HS Mode' to disabled. Note that this is not necessary under WinXP. * Do NOT press Reset button (or do NOT make a system power off) when BIOS updates Flash tables for ESCD and custom setup data. This short period of time (~2s) is signalled by a yellow warning message. * Info about dual DVI support and Windows OS: For dual DVI support and other features it is necessary to use a CD3 BIOS with build number >= 104 For Windows 2000/XP the newest available graphics driver (June 2007) on Intels website is version 14.25. Unfortunately this driver version makes problems when using both DVI-ports simultaneously or when hot-plugging a DVI monitor. To avoid these problems it is recommended to use version 14.24 (August 2006), which can be downloaded from: http://downloadcenter.intel.com/download.aspx?url=/11495/a08/win2k_xp1424.zip&agr=N&ProductID=1862&DwnldId=11495 Some hints after Windows driver is installed: - If nothing is seen on an attached analog/VGA monitor press CTRL-ALT-F1 - If nothing is seen on an attached DVi-Digital display press CTRL-ALT-F4 - Hot-Plugging of all display types in all combination works with driver V14.24 and BIOS >= 104 - Screen rotation of 90 and 270 degree is not supported with driver V14.24. Screen rotation is supported in newest driver V14.25.50, but this drivers hangs after hot-plugging a display Some infos about Windows graphics CUI (call it with CTRl-ALT-F12): - Analog/VGA monitor at bottom DVI connector (DVI-I) is shown as 'Monitor' - If two DVI-Digital displays are attached -> Display at bottom CD3-JIVE DVI connector (DVI-I) is shown as 'Digital Display' -> Display at top CD3-JIVE DVI connector (DVI-D) is shown as 'Digital Display 2' - If only one DVI-Digital display at top CD3-JIVE DVI connector (DVI-D) is attached, then this display is shown as 'Digital Display' * Infos about invalid CMOS data If the BIOS detects a bad checksum in CMOS data, CMOS is reset to default values during POST. The possible reasons for a bad CMOS checksum are: - An empty battery - A board with NO battery - Any software writes to CMOS and does not update the CMOS bytes which holds the checksum There exist three further options to set CMOS to default values: - Do a RTC reset (see documentation for more info) - Press CTL-ALT-F9 during POST (more info at top of this file) - Reset-in-Series option (more info at top of this file) * First start of a board with invalid CMOS data The first start of a board with invalid CMOS data will automatically enable a security/debug feature which is integrated by EKF into the BIOS. If this feature is enabled, all POST Codes, which are normally send to port 80 only, are additionally send to serial port COM1 (IO port 3F8h, 19200 Baud, 8N1). POST Codes are used to show BIOS progress step by step. If an external serial terminal is a attached to COM1 (or a Windows PC with opened Hyperterminal), the progress of the BIOS can be observed even in case of board failures caused by non-working memory, non-working graphics etc. The following two messages are shown after first start of a board with invalid CMOS data: WARNING 0251: System CMOS checksum bad - Factory Defaults loaded ERROR 0613: Com A configuration changed (possible reason: POST-Codes redirected) The following two messages are shown at every boot as long the BIOS has not tried to boot an OS: WARNING 02EB: POST-Codes currently redirected to COM1, 19200 Baud, 8N1 ERROR 0613: Com A configuration changed (possible reason: POST-Codes redirected) To go forward in the boot process press if above messages are shown. If you reboot the system when these two messages are shown, they will appear again and again. The debug feature is automatically disabled when the BIOS tries to boot an OS for the first time, at least message "Operating System not found" must appear. -------------------------------------------------------------------------------------------------------------------------- For any further questions contact EKF at: Email : support@ekf.de Internet : www.ekf.de or www.ekf.com 2007-06-06 EKF/cr
