Oops, you are right -- I misread the product description. they offer another low-cost model that only has two ports and by my best-guess looks like a hw/sw raid solution, ala promise. Yah. Even a hybrid card like that might be worth using (since it gives you redundancy before Linux loads), but every one I have read about either does not support Linux well (or at all) and/or eats data when a disk actually fails. In the Adaptec case, at least the former is true. Do you happen to know if the driver for that card is GPL'ed, i.e., to go into the mainstream kernel? adaptec has also posted the driver source on their website, linux.adaptec.com. Cool. Maybe we have a chance of getting it working on 2.2, then. Although, by all reports, 2.4 is improving in stability, I still wouldn't trust a server to it yet.

The hard drives were still connected to the ATA-100 connectors (IDE-2, 3), not the standard IDE UDMA33/66 ports (IDE-0, 1) That is likely going to be the problem. If the drives are connected to the RAID controller, then they will need to have a driver for that controller, even if you are not using the RAID features. Move the drives to the standard controller (the one on the VIA southbridge), and I bet things will start working.

if you are looking for hw ide raid on linux you might also try adaptec's 2400a.
it is an ata raid card derived from dpt's i2o raid platform. i have been using
one in one of my linux machines for a few weeks now without any problems.
adaptec has 2.2 driver disks for the popular distros on their web site you have
to roll your own for 2.4, and patch the driver in for 2.4 kernels less than
2.4.10 (i think, can't remeber when linus did the merge). at any rate, i think
i still have my redhat 7.1 driver disk if anybody needs one.
storage review did a review a few months back, i'm sure you could dig on their
site and find it, they have some comparisons with the 3ware cards.

Unfortunately, the Adaptec cards are limited to two channels and cost twice as much as 3Ware's offerings, but it looks to be the best we can do. i think you might have the wrong card in mind, the 2400a has four ata-100 channels. they offer another low-cost model that only has two ports and by my best-guess looks like a hw/sw raid solution, ala promise. the 2400a is a full hw solution, four highpoint ata-100 chips controlled by a i960rs. it also supports up to 128m of cache and ships with 32m (or 64m, can't remember). Do you happen to know if the driver for that card is GPL'ed, i.e., to go into the mainstream kernel? yep, it is in the later 2.4 kernels. like i said before i think it was 2.4.10 that first included the Adaptec I2O scsi controller, but don't hold me to that revision, i was used to hand patching the driver in and forgot when i stopped. i know 2.4.12 has it, i just built that two days ago. adaptec has also posted the driver source on their website, linux.adaptec.com.

Apparently, someone in marketing must've noticed that people were buying their $300 RAID cards, then turning around and selling $10K+ turnkey RAID systems... so now that's what they're going to do, instead. *sigh* The EOL announcement was made as of early October (late September?), but they won't cease production/support until 12/31. -Ken P.S. Note that they're discontinuing it to keep others from competing with their RAID box product line, *not* because the cards were selling poorly. Can anyone say wide open market niche? I just hope whoever fills it is as Linux-friendly as these guys were. ** To unsubscribe from this list, send mail to [EMAIL PROTECTED] with the following text in the *body* (*not* the subject line) of the letter: unsubscribe gnhlug **

Furthermore, these cards are not RAID controllers. They are IDE controllers with special BIOSes. The BIOS implements RAID for real-mode, and in protected mode, it is up to the device driver. The practical upshot is, they are the moral equivalent of software RAID (using the Linux 'md' driver, for example), but with a proprietary format and a single vendor. I would recommend just disabling the thing, and using Linux software RAID. Yes, I know they are not real RAID controllers; the chip is integrated on the motherboard. However, I tried booting the install program without the raid array defined (I don't know how else to disable the hardware) and it still couldn't recognize the hard drive(s).

I wouldn't care about it at all, except there is no way to disable it completely, thus it always uses an IRQ and some address space, which annoys me. :) However, I tried booting the install program without the raid array defined Does that mean the drives were connected directly to the IDE controller in the VIA southbridge chip? Or that you simply had the RAID controller in no RAID mode? [sales pitch snipped :o)] LOL.
