DISCUSSION: Promise FastTrack PDC20378 PATA or RAID

This thread is to discuss the article titled:
Promise FastTrack PDC20378 PATA or RAID

If you own a motherboard with the Promise PDC20378 FastTrack 374 SATA/RAID controller you probably know the same frustration as me. Part of the problem with the PDC20378 and Linux is the fact that the PDC20378 has both SATA and PATA ports in the same device. The standard Linux implementation for ATA devices does not support a device with some SATA and some PATA ports. Devices are either SATA or PATA (not BOTH). Add to that the fact that Linux does not understand the RAID array metadata for the PDC20378. Here are some of the issues with the PDC20378.[LIST] [*]Promise has a proprietary RAID driver only for kernel version 2.4

Hey Erik,

I am trying to apply the patch to a vanilla kernel. I have downloaded the kernel from and have created a bz2 file from your patch. Then i cd to the kernel source dir and use the command:

bzcat /usr/src/linux- | patch -p1
and i get the output:

Patching file drivers/scsi/libata-core.c
patch: **** malformed patch at line 4: ap->mwdma_mask = ent->mwdma_mask;
Am i doing some thing wrong in the way i use the patch? Havn't patched my kernel in a long time.

Hope you know what the problem is
