Before only the timings for master were set. Datasheet can be found here: ftp://ftp.vtbridge.org/Docs/Storage/DS_VT6421A_100_CCPL.PDF Surprisingly, a slave drive works without this patch. According to the datasheet, the controller by default derives the DMA mode from the Set Features command issued to a drive. Not sure about the PIO timings, though. The real problem is that the timings for the master effectively are the ones tuned for the slave. If these support different UDMA-settings, there is trouble, especially when the slave supports a higher UDMA than the master. Anyhow, using the same mechanism for both master and slave seems like a good idea.
