Venturis Readme March 7, 1996 This file covers the following: * Supported Video Resolutions * CPU Processors * Documentation Corrections * Late Breaking Information SUPPORTED RESOLUTIONS Your system can support a wide range of resolutions. Should you want to increase the resolution of your system, review the instructions in your User's Guide for Setting High Resolution Mode for Your Monitor Display. Before you set the resolutions, check your monitor manual to see that your monitor can support the resolution you select. The following are the resolutions your system supports for Windows for Workgroups and Windows 3.x. If you are using Windows 95, select drivers from Windows 95. ____________________________________________________________ Resolution Horizontal Vertical Dot Video Memory Mode Freq.(KHz) Freq.(Hz) Clock(MHz) Size ____________________________________________________________ 640X 480X 8 31.5 60(NI) 25.175 1 MB/2 MB 640X 480X 8 37.9 72(NI) 31.500 1 MB/2 MB 640X 480X 8 37.5 75(NI) 31.500 1 MB/2 MB 640X 480X15 31.5 60(NI) 25.175 1 MB/2 MB 640X 480X15 37.5 72(NI) 31.500 1 MB/2 MB 640X 480X15 37.5 75(NI) 31.500 1 MB/2 MB 640X 480X16 31.5 60(NI) 25.175 1 MB/2 MB 640X 480X16 37.5 72(NI) 31.500 1 MB/2 MB 640X 480X16 37.5 75(NI) 31.500 1 MB/2 MB 640X 480X24 31.5 60(NI) 75.000 2 MB 640X 480X24 37.9 72(NI) 65.000 2 MB 640X 480X24 37.5 75(NI) 65.000 2 MB 800X 600X 8 35.1 56(NI) 36.000 1 MB/2 MB 800X 600X 8 37.9 60(NI) 40.000 1 MB/2 MB 800X 600X 8 48.1 72(NI) 50.000 1 MB/2 MB 800X 600X 8 46.8 75(NI) 50.000 1 MB/2 MB 800X 600X15 40 60(NI) 40.000 1 MB/2 MB 800X 600X15 48.1 72(NI) 50.000 1 MB/2 MB 800X 600X15 46.8 75(NI) 50.000 1 MB/2 MB 800X 600X16 40 60(NI) 40.000 1 MB/2 MB 800X 600X16 48.1 72(NI) 50.000 1 MB/2 MB 800X 600X16 46.8 75(NI) 50.000 1 MB/2 MB 800X 600X24 37.9 60(NI) 77.000 2 MB 800X 600X24 48.1 72(NI) 94.500 2 MB 800X 600X24 46.8 75(NI) 94.500 2 MB __________________________________________________________ Resolution Horizontal Vertical Dot Video Memory Mode Freq.(KHz) Freq.(Hz) Clock(MHz) Size ____________________________________________________________ 1024X 768X 8 35.5 43(I) 44.900 1 MB/2 MB 1024X 768X 8 48.4 60(NI) 65.000 1 MB/2 MB 1024X 768X 8 56.5 70(NI) 75.000 1 MB/2 MB 1024X 768X 8 60.0 75(NI) 80.000 1 MB/2 MB 1024x 768X15 35.5 43(I) 44.900 2 MB 1024x 768X15 48.9 60(NI) 65.000 2 MB 1024x 768X15 56.5 70(NI) 75.000 2 MB 1024x 768X15 60.2 75(NI) 80.000 2 MB 1024x 768X16 35.5 43(I) 44.900 2 MB 1024x 768X16 48.9 60(NI) 65.000 2 MB 1024x 768X16 56.5 70(NI) 75.000 2 MB 1024x 768X16 60.2 75(NI) 80.000 2 MB 1280X1024X 4 46 45(I) 75.000 1 MB/2 MB 1280X1024X 4 65 60(NI) 110.000 1 MB/2 MB 1280X1024X 8 46 45(I) 75.00 2 MB 1280X1024X 8 65 60(NI) 110.00 2 MB 1280X1024X 8 77.7 72(NI) 135.00 2 MB 1280X1024X 8 79.5 75(NI) 135.00 2 MB ____________________________________________________________ Note: I denotes Interlaced, NI denotes Noninterlaced CPU PROCESSORS Your Venturis is now also available in 120 MHz, 133, 150, and 166 MHz. These new CPUs mean your Venturis now comes with one of the following advanced microprocessors (CPUs): * 75 MHz * 90 MHz * 100 MHz * 120 MHz * 133 MHz * 150 MHz * 166 MHz Should you wish to upgrade to a 150 MHz or 166 MHz, you must have BIOS Version 2.01 or greater. Note that Digital reserves the right to discontinue any of these models or to add new models as more advanced CPUs are developed. DOCUMENTATION CORRECTIONS IR Adapter The IR adapter is a separate option that plugs into the serial port. Plug and Play Kit A DOS-bootable Plug and Play diskette is only available for those who receive their systems without a Digital installed hard disk drive. If you are a Windows 95 user, Plug and Play comes with Windows 95. Configuring Your Computer: BIOS Setup Quiet Boot is not included in BIOS Setup. This features was listed in your User's Guide as part of the Main Menu Options. Your BIOS Setup has some additional features described in the following tables. MAIN MENU _______________________________________________________________________ Menu Field Settings Comments _______________________________________________________________________ Diskette drive A 1.44 MB, 3 1/2 Sets the size and density of Diskette drive B 2.88 MB, 3 1/2 Not installed 1.2 MB, 5 1/4 720 KB, 3 1/2 ________________________________________________________________________ ADVANCED MENU _______________________________________________________________________ Menu Field Settings Comments _______________________________________________________________________ Monitor Auto Sets Color or Monochrome as Color your monitor. Auto is for Monochrome auto detection. If Auto fails to set the monitor correctly, use this field to change the setting to your monitor type. Plug & Play Yes/No Select "Yes" if you are using a Plug & Play operating system, such as Windows 95. Otherwise, select "No." Reset Configuration Yes/No Select "Yes" to clear the Data the system configuration data and "No" not to clear it. Setting this field to "Yes" is useful should your configuration area ever be destroyed or corrupted. The "Yes" setting then forces the system to clear the system configuration area of all system resources and Plug & Play information and thereby prevent system resource conflicts. Once the system resources are erased, the BIOS then automatically sets the field back to "No" so as to prevent further erasures. _______________________________________________________________________ SECURITY MENU ______________________________________________________________________ Menu Field Settings Comments ______________________________________________________________________ Keyboard Quick Lock Enable To enable this feature Disable you must: * Set a Supervisor Password and a User Password if you want one. * Enable Password on Boot * Enable Power Management * Enable Suspend Lock System * Select a keyboard sequence for Quick Suspend When you press the keyboard sequence (for example, [Ctr]+[Alt]+[Esc]), the keyboard and mouse lock and the system goes into system suspend. To unlock the keyboard and mouse and wake up the system, you must enter your supervisor password. If you also entered a user password, you can use alternatively the user password to unlock the system. ____________________________________________________________________________ POWER MENU ______________________________________________________________________ Menu Field Settings Comments ______________________________________________________________________ Suspend lock Yes When enabled, you can press the system No Quick suspend keyboard sequence (for example, [Ctrl]+[Alt]+[Esc]) to lock both the mouse and keyboard and puts the system into system suspend. Alternatively, the system can go into Suspend Lock when the your system reaches the time period set in your System suspend timer. To enable Suspend lock system, you must: * Set a Supervisor Password. and a User Password if you want one. * Enable Power Management * Select a Quick suspend sequence. If you want system inactivity to also trigger the Suspend lock system feature, enter a time period for System suspend timer. To wake up the system, enter the Supervisor Password. Alternatively, if you have set a User password, you can enter it. Quick suspend Disabled Enabling this option allows you to [Ctrl-Alt-Esc] suspend your computer immediately [Ctrl-Alt-Scroll by pressing the key sequence you Lock] selected. (See the center column [Ctrl-Alt-F1 - F10] for settings for this option.) [Ctrl-Alt-1 - 0] Keyboard or mouse activity unlocks the keyboard and mouse unless you have enabled Suspend lock system. (See Suspend lock system in this Readme.) _________________________________________________________________________ Fixed Disk boot This option is as described in your User's Guide. Note that it is a good method of protecting your hard disk against boot sector viruses. Main Logic Board The VGA BIOS may be combined with the ROM BIOS. As a result your system does not have a VGA (Video) BIOS as depicted in Figure 4-7 "Main Logic Board Components". Main Logic Board Connectors - E in Figure 4-8 is mislabeled. It is a PCI IDE drive. Your main logic board may contain a battery instead of a real-time clock (RTC). The directions for changing the RTC are in your User's Guide. They are basically the same. However, when you remove the old battery or RTC, note it orientation. Replace the new battery or RTC in the same orientation. J35 is a jumper that is included only on MLBs with 4 SIMM sockets. This jumper controls VRE CPU voltage and is set correctly for the CPU installed on your system. Should you later upgrade the CPU, you may have to change this setting. (See "CPU Clock/Voltage Regulator Jumpers" below.) Installing Additional Computer Memory Your computer may come with four SIMM sockets on the main logic board. Using these SIMM sockets, you can increase the amount of main memory on your system up to a maximum of 128 MB. The following memory map shows possible memory configurations.

If your system came with a factory installed IDE CDROM, you must make this change. Workgroups for Windows or Windows 3.X and IDE CDROMs When using an IDE CDROM with Workgroups for Windows or Windows 3.x and an IDE CDROM, such as the Mitsumi CDROM, make sure that in your CONFIG.SYS you load the driver for the CDROM after you load the CMD IDE driver. For example, for the Mitsumi CDROM, the the CONFIG.SYS should include the following lines: DEVICE=C:\QUICKCMD\CMD640X.SYS /A33 /I15 /L DEVICE=C:\MTM\MTMCDAI.SYS /D:MTMIDE01 If your system includes as factory installed CDROM, this change to the CONFIG.SYS file is already made. A generic IDE CDROM driver is included in you QUICKCMD directory. Should you later add a CDROM and are having difficulty with your CDROM's performance, you may find this generic driver resolves the problem. Also note that that you should connect the hard drives to IDE0 and the CDROM should be connected to IDE1. Additional VGA Adapter If you install a VGA adapter that requires the use of an IRQ, you must set the onboard VGA to "Enabled" in the BIOS Setup.
