Apple Macintosh System 7.5 - Manual (Page 98)

The Update Driver option is not available in the Drive Setup utility.
Problem: When you try to choose Update Driver from the Functions menu, it
is dimmed and not available.
Cause: Some IDE hard disks must be reinitialized before you can update the
driver.
Solution: Back up all the files on the IDE hard disk (onto another disk), and
use Drive Setup to reinitialize the IDE hard disk. For instructions on
reinitializing the hard disk, see the manual that came with your computer.
Not enough memory to use the Installer
Problem: When you try to use the Installer, you see a message that the
Installer is out of memory.
Cause: There’s not enough memory available to open the Installer. Usually
this means that your disk cache or RAM Disk is set too high.
Solution: Quit all open application programs. Also, open the Memory control
panel, set your disk cache to the lowest possible setting, and turn on Virtual
Memory.
Not enough memory
Problem: When you try to use the Installer, you see a message that your
computer doesn’t have enough memory.
Cause: Your computer has less RAM than is required to use System 7.5,
QuickDraw GX, PowerTalk, OpenDoc, or a combination.
Solution: For memory guidelines, see “Check Your Computer’s Built-in
Memory” in Chapter 1 (“Installing System Software”) of this book. If
necessary, contact your Apple-authorized reseller for information about how
to purchase additional memory.
