According to Epox web site at

the card is supported but not with hardware RAID.
Thank you, Anders, for the link. It appears that for the sake of good ol' American-style Intellectual Property (which is even more viril than the GPL), EPoX has covered the chips with stickers. I think this information about using them as RAID devices is out of date, if my wires aren't crossed (which they often are). If push came to shove, you could set up the controller as a regular IDE device, not a hardware RAID device, and use the Linux kernel to configure software RAID with a small performance hit. Let's see what we can do about the hardware side first, though. Using `make menuconfig` in a vanilla linux-2.4.17 source tree (this should work with Hubert's tree as well), enable the stuff below. This is not a complete configuration, mind you, but it should cover what's necessary to make stuff work: Code maturity level options ---> [*] Prompt for development and/or incomplete code/drivers # Keep in mind that this is all to be considered experimental. Don't # cry to us if your entire /usr filesystem gets hosed because of an # error from using the IDE-RAID card. Multi-device support (RAID and LVM) ---> [*] Multiple devices driver support (RAID and LVM) <*> RAID support <*> Linear (append) mode <*> RAID-0 (striping) mode <*> RAID-1 (mirroring) mode <*> RAID-4/RAID-5 mode <*> Multipath I/O support <*> Logical volume manager (LVM) support # This is where RAID business get's taken care of. If you're not # mounting / from these devices (I wouldn't), you can make them as # modules. ATA/IDE/MFM/RLL Support ---> IDE, ATA, and ATAPI Block devices ---> <*> Enhanced IDE/MFM/RLL disk/cdrom/tape/floppy support <*> Include IDE/ATA-2 DISK support [*] Generic PCI IDE chipset support [*] Generic PCI bus-master DMA support [*] Boot off-board chipsets first support # This option ^ Enables booting from the IDE-RAID first, but is not # necessary. [*] Use PCI DMA by default when available [*] HPT366 chipset support [*] PROMISE PDC202{46|62|65|67|68} support [*] Special UDMA Feature [*] Special FastTrak Feature # These enable the core chips of the most common IDE-RAID cards. # Don't forget to build the drivers for your motherboard ATA # controller! <*> Support for IDE Raid controllers <*> Support Promise software RAID (Fasttrak(tm)) <*> Highpoint 370 software RAID # This is where IDE-RAID business get's taken care of. Again, if # you're not mounting / from these devices (I wouldn't), you can make # them as modules to reduce kernel size. There's more information in linux/Documentation/ide.txt and other places on the Web, but this is a start. You will have much documentation to read if you plan to make a successful run with this card. If I were you, I'd use lots of partitions on the array, putting significant pieces of the filesystem (/usr, /opt, /home, and so forth) on their own partitions. KEEP REGULAR BACKUPS. I'd keep / (which also means /bin, /sbin, /etc, and others) on a normal disk if I were you, though. Let's figure out what chipset that is so we can trim this down even further...somebody (like you, Jaakko) call/email EPoX. -- -=|JP|=- Need a good geek? I'm unemployed!
