I received a response from Synchrotech, the supplier of one of my cards. He said that they were under NDA with their manufacturing partner and couldn't offer the full specs. However he could tell me the specific bridge chip:
JMicron JMB368 PCIe to PATA controller
A quick google led me to their website where they advertised this chipset as being supported by these OS's:
OS JMB368 Windows 2K/XP/2003/Vista BSD/FreeBSD FreeBSD 5.5 or above BSD/OpenBSD OpenBSD 3.x Linux/Redhat/Fedora Fedora Core 6 Linux/Suse Suse 10.1 Linux/Gentoo Gentoo 2006.1 liveCD Linux/Ubuntu Ubuntu 6.10 Linux/RHEL RHEL 5 Linux/CENTOS CENTOS 5 Linux/Suse Enterprise Suse Enterprise 10 Linux/Other Linux Distrbution Kernel 2.6.18.2 or above Unix/SCO OpenServer SCO OpenServer 6 Unix/SCO UnixWare SCO OpenServer 7.1.4 Unix/Solaris Solaris 10 NAS/FreeNAS FreeNAS 0.65 NAS/OpenFiler OpenFiler 2.3 NAS/Opene-NAS NAS/Opene-NAS MAC OS X MAC OS 10.4.3*
It seems support for this chipset is already available in the kernel. Is this enough information to enable DMA & PIO support for this device?
