22. CONFIGURING YOUR COMPUTER

Before you format or partition your new drive, you must con- figure your computer’s BIOS so that the computer can recog- nize your new drive.

1 Turn your computer on. As your computer starts up, watch the screen for a message describing how to run the sys- tem setup program (sometimes called BIOS or CMOS setup). This is usually done by pressing a special key, such as DELETE, ESC, or F1, during startup. See your computer manual for details. Press the appropriate key to run the system setup program.

2 Enable LBA mode if it is available. Many BIOS use the logi- cal block addressing (LBA) mode to access drives with capacities greater than 528 Mbytes.

3 If your BIOS provides automatic drive detection (an “Auto” drive type), select this option. This allows your computer to configure itself automatically for your new drive.

If your BIOS does not provide automatic drive detection, select “User-defined” drive settings. If your computer supports LBA addressing, enter the LBA cylinder, head and sector values for your drive from the table at the top of the next column. If your computer does not support LBA ad- dressing, enter the CHS values from the table.

Note. Set the write precomp or landing zone parameters to zero.

33A. INSTALLATIONaUSING DISK MANAGER

1 Boot your computer from a bootable DOS diskette (use MS DOS Version 5.0 or later). Booting from a diskette ensures that the Disk Manager installation does not conflict with any terminate-and-stay-resident (TSR) programs.

2 Insert your DiscWizard diskette. The Disk Manager soft- ware is stored on this diskette.

3 At the DOS prompt, type DM and press ENTER.

4 Follow the onscreen instructions until you see the Select an Installation Option menu.

5 Select either (E)asy Disk Installation or (A)dvanced Disk Installation.

Because DOS computers cannot access partitions larger than 2.1 Gbytes, Disk Manager may have to divide your hard drive into multiple partitions. If you select (E)asy Disk Installation, Disk Manager creates a 2.1-Gbyte partition and a second partition using the remainder of your hard disc. However, if most of your files are smaller than 50 Kbytes, you may want to create several smaller partitions to make more efficient use of your hard disc space.To create smaller partitions, select (A)dvanced Disk Installation from the Disk Manager main menu.

4Save the settings and exit the System Setup program (your computer will automatically reboot).

We recommend that you use Disk Manager to partition and format your drive, especially if your computer was built before mid-1994.See Section 3A, “Installation Using Disk Manager,” below. If you do not want to use Disk Manager, you can use the standard DOS commands to partition and format your drive, as described in Section 3B.

6At this point, Disk Manager lists all the hard drives that it can recognize. You should see your new Seagate drive and your existing hard drive, if any.

If any hard drive is not recognized, exit Disk Manager and turn off your computer. Check all cables, jumpers and BIOS settings. Then start at step 1 to run Disk Manager again.

7If Disk Manager recognizes all your drives, select the drive you want to install and press ENTER. Disk Manager parti- tions and formats the drive. If your new drive is the master drive (Drive C), Disk Manager also configures the drive so that you can boot from it.

Note. If your computer cannot accommodate hard drives with capacities greater than 528 Mbytes, Disk Manager installs a Dynamic Drive Overlay (DDO) on your hard disc. If this driver has been installed, you should see a blue Disk Manager banner each time you boot your computer. See the Disk Manager online manual for details.

8Follow the instructions in the post-installation screens.

YOU’RE DONE!
