============================================ Second Hard-Disk Drive Module Release Notes ============================================ This document provides information on the following subjects: * Boot options and characteristics of the second hard-disk drive module * Microsoft(R) Windows NT(R) operating system issues * Creating docked and undocked system profiles (for C/Dock users only) --------------------------------------------------------------------- Boot Options and Characteristics of the Second Hard-Disk Drive Module --------------------------------------------------------------------- * The second hard-disk drive module may be used as a boot device in the system modular bay if you partition and format it properly. See the Dell(TM) Latitude(TM) C-Family Second Hard-Disk Drive Advanced Setup document, which can be downloaded from Dell's World Wide Web site at http://www.dell.com/support. NOTE: To enable your computer to perform a suspend-to-disk (S2D) operation when using the second hard-disk drive module as the boot device, you must have an S2D partition on your second hard-disk drive module. Use the Suspend-to-Disk utility to create the S2D partition on your hard-disk drive. The S2D partition receives the system data transferred during S2D mode. You can download the latest version of the Suspend-to-Disk utility from Dell's World Wide Web site at http://www.dell.com/support. To set up the S2D partition, see the readme.s2d file that is downloaded with the Suspend-to-Disk utility. The hard-disk drive requires S2D version 3.6.6 or later. * The second hard-disk drive module may not be used as a boot device when it is in the C/Dock media bay due to a limitation with some operating systems and the Peripheral Component Interconnect (PCI)-to-PCI bridge. * The key combination will not turn off the drive in the C/Dock media bay. * Hard-disk drive letter assignments depend on the boot sequence and the characteristics of the partitions on each hard-disk drive in your computer and the C/Dock media bay. To avoid difficulty in identifying hard-disk drives, assign volume labels to each hard-disk drive partition. You assign volume labels when you format a partition. * The second hard-disk drive module is assigned the letter 'C' only if the drive is bootable and specified as the first boot device in the Setup program. * Some operating systems and application programs, such as MS-DOS(R) and FDISK, are unable to communicate with the second hard-disk drive module if the module is installed in the C/Dock media bay. This inability to communicate is due to a limitation with some operating systems and the PCI-to-PCI bridge. * You may specify a password on any or all of the hard-disk drives installed in your system. * If you specify the same password for every hard-disk drive, you are only prompted once to enter the password. * The password resides on the hard-disk drive and remains there if it is moved to another system. NOTE: If you do not enter a password or enter an incorrect password, the hard-disk drive is locked and turned off. In this situation, the system boots from the next available boot device. If no boot device is available, the system shuts down. * During reboot, you are not prompted to enter a password for a hard-disk drive module that is installed in the C/Dock media bay. -------------------------------------------- Microsoft Windows NT Operating System Issues -------------------------------------------- * Because the Windows NT operating system uses the input/output (I/O) address of the second hard-disk drive module, the hard-disk drive in the modular bay is detected as Disk 1 and is not assigned the drive letter C unless the primary hard-disk drive is removed or locked. If you intend to install Windows NT on the second hard-disk drive module, you must first copy all of the installation files to the second hard-disk drive module, and then remove or lock the primary hard-disk drive before installing the operating system. -------------------------------------------- Microsoft Windows NT and the CMD Driver -------------------------------------------- If one of the following conditions is met, the CMD driver is no longer needed on your computer and you need to remove it. * A version of the file ATAPI.sys dated 1/28/98 or later is installed on the computer * Service Pack 4 is installed on the computer * Softex Docking Services are installed on the computer To remove the CMD driver, perform the following steps: 1. Click the Start button, point to Settings, and click Control Panel. 2. Double-click SCSI Adapters and click the Drivers tab. 3. If CMD CSA-646U Ultra DMA IDE Adapter does not appear in the list of drivers, skip to step 6. If CMD CSA-646U Ultra DMA IDE Adapter does appear in the list of drivers, perform the following steps: a. Click CMD CSA-646U Ultra DMA IDE Adapter and click Remove. Click Yes when the following message appears: Are you sure you want to remove this driver? b. Click IDE CD-ROM (ATAPI 1.2)/Dual-channel PCI IDE Controller and click Remove. c. Click Yes when the following message appears: Are you sure you want to remove this driver? 4. Click Add. The Install Driver window appears. 5. Click Standard mass storage controllers under Manufacturers. 6. Click IDE CD-ROM (ATAPI 1.2)/Dual-channel PCI IDE Controller under SCSI Adapters. 7. Click OK. A window explaining that the required files are already installed on your hard disk may appear. Click Yes to use the files that were factory installed. 8. Click Yes on the System Settings Change window to restart the computer. 9. When your computer restarts, download the ata-fixi.exe file from ftp://ftp.microsoft.com/bussys/winnt/winnt-public/fixes/usa/NT40/hotfixes-postSP3/ atapi-fix/. 10. Run ata-fixi.exe. 11. Shut down and restart your computer when prompted. NOTES: If your computer is shipped from Dell with Microsoft Windows NT 4.0 and Softex Docking Services installed, it has an updated version of the ATAPI.sys file and does not require the CMD driver. If your computer is shipped from Dell with an ATAPI.sys file dated 1/26/98 or later (whether or not the Softex Docking Services are installed), your computer does not require the CMD driver.
