Info on this seems to be fairly hard to track down. With a bit of Googling, I turned up this much: Apparently the 2100s requires a dpt_i2o.o module. This is (or was; I can't find an actual link) available from Adaptec, and it *may* be the same module that is now part of recent 2.4.x kernels (associated with "Adaptec I2O RAID support"). In any case, this link the closest I can to working instructions ... http://www.togaware.com/linux/survivor/Load_RAID.html ... and it does not describe a complete process -- though it does discuss compiling the module for kernel 2.2.19 and concerting the Debian bootdisks to use that kernel. I suspect you will need eventually to compile a kernel with initrd support so it can load the needed modules before trying to mount the root filesystem on the RAID array. Or you will need to boot/init from a different location -- were I facing this problem, I'd add a small (10-20 GB or so, small by today's standards) IDE drive and use it as boot media and the root filesystem ... mounting the RAID array at a point appropriate to whatever use calls for a RAID array (/home ? some database directory?). For more information, try Googling "linux Adaptec 2100S debian". Especially if you read German (I don't), you'll find a lot. - To unsubscribe from this list: send the line "unsubscribe linux-newbie" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.linux-learn.org/faqs
