Biggly,
Starting from Ubuntu 8.10, it cannot discover the IDE HDD on the SS4200. I believe this is because the IDE modules are all removed from the default kernel. You can recompile the kernel to add back the driver.
Direct install the 8.10 CD is still has problem on discovering the IDE...
I have a question on DMA on IDE port. I have tried Ubuntu 8.04 and Debian 5.0 and both fail to enable the IDE DMA.
I tested all the BIOS IDE setting from Enhanced-IDE/RAID/AHCI to legacy mode. Only legacy mode give DMA but only two SATA drives are populated.
I recompiled the Kernel...
