High-performance video and Ultra ATA storage device control are provided by the embedded Intel 815E chipset. Dual high-performance LAN operation is provided by an Intel GD82559ER Fast Ethernet adapter chip (LAN1) and the embedded Intel 815E chipset (LAN2). The two LAN adapters can be configured to allow the VMIVME-7750 to access two separate, physical networks. Each LAN adapter is capable of running 10BaseT and 100BaseTx. To optimize performance of each of these PCI-based subsystems, the user must install the driver software located on the distribution CD-ROM provided with the unit. Detailed instructions for installation of the drivers during the installation of Microsoft Windows 98 Second Edition (SE), Windows NT Workstation (NTW) 4.0 and Windows 2000 Professional operating systems are provided in the following sections. B 86 B VMIVME-7750 Product Manual Using USB Keyboard/Mouse with Microsoft Windows Operating Systems This section applies if either a USB keyboard or USB mouse is connected. It does not apply if a PS/2 keyboard and mouse are used. Windows 98SE/Windows 2000 The use of a USB keyboard/mouse with an operating system that supports USB devices requires changing the default BIOS settings before and after the installation of Windows 98SE/2000. ‘Legacy USB Support’ must be enabled in the BIOS to allow a USB keyboard/mouse to operate as a PS/2 device during the installation of Windows 98SE/2000. After the installation is complete, the computer will restart and boot Windows 98SE/2000. As the computer is restarting to boot the operating system for the first time, ‘Legacy USB Support’ must be disabled, and ‘Assign Interrupt to USB’ must be enabled. If Legacy USB Support is not disabled, Windows 98SE/2000 will attempt to load a device driver for a device (USB) that is not present at that point. See “BIOS Setup” on page 87 for guidelines on changing BIOS settings. A suggested workaround to this situation is to connect a PS/2 keyboard and mouse, disable ‘Legacy USB Support’ and enable ‘Assign Interrupt to USB’ in the BIOS, and install Windows 98SE/2000. At some point after the installation is complete, replace the PS/2 keyboard and mouse with a USB keyboard and mouse and enable ‘Legacy USB Support’ in the BIOS. This approach might be easier since you don’t have to worry about making changes to the BIOS at exactly the right time. Windows NT 4.0 The use of a USB keyboard/mouse with an operating system that does not support USB devices requires changing the default BIOS settings. ‘Legacy USB Support’ must be enabled in the BIOS to allow a USB keyboard/mouse to operate as a PS/2 device. This setting must be enabled prior to the installation and during the operation of Windows NTW 4.0. See “BIOS Setup” on page 87 for guidelines on changing BIOS settings.
