MacPro ESATA card for everthing

This post is in regards to adding an ESATA card to a MacPro.  You’re probably thinking, why add an ESATA card when you have 2 SATA ports that can be converted to ESATA with a simple cable.  The SATA ports onboard are only supported in AHCI mode.  Whenever you boot into Linux or Windows you’re automatically put into legacy mode which does not see the extra ports aka your drives.
My best candidate for an ESATA card was the Adaptec 1225SA.  This card has support for Linux RPMS and Windows drivers out the wazoo. (I’m not a fan a recompiling the kernel for drivers that should already be there and I like the official support)  However, Adaptec has no support for MacOS.
I received a 1225SA revision 3 which had a Silicon Image chipset and a Silicon Storage Technology chip.

The chipsets were:

Silicon Image
SII3132CNU
QN4863.1-17
0725
AD02CX2

Silicon Storage Technology
39VF040
70-4C-NHE
0721003-K

The highest drivers that are supported from the Silicon Image website are 10.5.1…Boo!  I installed several variants, but alas it was for naught.  My search continues….
