New system consideration
–Seagate's DiscWizard Starter Edition disc installation software is
designed to make building a new system as easy as possible. This software supports several
controller card models. DWSE also provides the convenience of a fast partition and format saving
nearly an hour over the operating system tools.
When building a new system, if you are using a ATA/133 PCI controller card which includes new
ATA or ATAPI disk device drivers, the Windows NT operating system installation will pause briefly
and ask for you to insert a OEM floppy diskette. This pause for new "SCSI or RAID adapter"
drivers happens soon after the boot near the beginning of the installation. See your controller
documentation for specifics.
Adding a drive to an existing system
– The installation procedure is relatively easy if your original
boot drive is attached to the motherboard and your new drive is attached to the controller card as
additional storage. If you want your new drive to become the boot drive, your system BIOS must
have an option to control the boot device or to release boot control from the Primary Master to the
controller card. This is sometimes listed as "boot from SCSI".
Seagate's DiscWizard 2003 disc installation software for Windows is designed to make adding a
new drive to a system as easy as possible.
11. Macintosh System X on a traditional motherboard
Most Apple Macintosh systems have a native limitation of 137GB supporting ATA interface disc
drives. Operating system support for 48-bit LBA addressing begins with OS X 10.2/9.2.2.
BootROM support for 48-bit is also a requirement. For further information, see article ID: 86178
“Macintosh: Using 128 GB or Larger ATA Hard Drives” at info.apple.com.
48-bit hard drives attached to systems built prior to OS X 10.2/9.2.2 and without adequate
BootROM support will be limited to 137GB. Otherwise, you could consider the purchase of an
Ultra ATA/133 PCI Controller Card specifically designed for Macintosh computers, available from
most retail and online computer stores.
12. Macintosh System X on a PCI controller card
New controller cards are available that support ATA interface disc drives through their own
onboard BIOS and custom Mac OS device drivers. Companies which are known to manufacture
ATA controller cards that support Mac OS drives greater than 137GB are SIIG, Inc
