Mac Forum / General / Hardware / August 2004

I wanted to install a 200GB Seagate Ultra drive into a G4 450. This mac
will not allow >130GB without a new disk controller. I installed a SIIG
Ultra PCI based disk controller. It works & boots okay. But shows up as
a SCSI device. Is this normal? Do all PCI add on disk controllers show
as SCSI? Or just this SIIG company?

Curiously, under Apple System Profiler, under ATA only the drives on the
motherboard controller show up.

Under PCI/AGP Cards an entry for a SCSI device shows (I had no SCSI
devices prior to this).

Under SCSI, there was a new entry showing my two newly installed drives
(both ATA IDE drives, one a newer Ultra and the other an older IDE) as
both SCSI drives!

Curiously, their manual says it should show under ATA devices. No
mention of it showing as SCSI.

Seems to be working okay and boots the system fine from a ATA/IDE drive
installed under this SIIG card.
=================
Details belowL:

I bought & installed:

SIIG Ultra ATA/133 PCI  5year warranty IDE controller @ $74.99
Seagate 200GB Barracuda 7200 8MB cache SEA ST3200822A

and installed in a G4 450 running 10.3.4

Drive came with a Ultra cable. Seagate was an Ultra drive. While at it  
I installed an older WD 10GB drive (non Ultra) I had unused laying
around on same Ultra cable Seagate as master WD as slave. This resulted
in slow performance with both on same Ultra cable so switched to Seagate
on Ultra cable on one bus and older WD drive on another older cable on
the other IDE bus of SIIG card. That worked with both as Master. There
are now 4 IDE drives in this G4 now.

Drives & card are working and boots mac with OSX on Seagate drive under
SIIG card running OSX 10.3.4.
