Search for tagged command queueing and DLTA and IBM; you will be rewarded with many horror storries about the drive electronics not being able to keep up on these drives, when writing near the spindle. This normally doesn't happen until the disk is almost full, with Windows FS's, which will usually place your machine safely out of warranty. -- Terry To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

Well, thanks :) Anyhow, the problem at hand is more like bad chipsets, there is ALOT of ATA chipsets thats not working right when used the way needed for tagged queuing. That said, the IBM DTLA's series of drives are extremely picky about power (that makes them unusable in at least California right :)) which I've seen cause trouble on highly loaded machines. However I run 4 of them here locally with tags, and they get about as much beating as they can handle, not a single error yet, so it definitly works, you just need the right environment for them. So what chipset does you machine have ? that could very well be the problem here. -Søren To Unsubscribe: send mail to [EMAIL PROTECTED] with unsubscribe freebsd-hackers in the body of the message

Excuse me : I meant for the common mortal, with prices more in line with what can be expected from Asus or Abit These *are* prices for common mortals: Tyan Tiger 760MP mobo $220 2x Palomino 1.2GHz MP $160 x 2 total: $540 Surely one can afford that. Heck the K6-2/450 I used for 2.5 years cost me $225 and the Tyan Trinity100 mobo was like $125; that was $350 just for that. OR go with the Tyan Thunder 2/dual 10/100 NICs + dual U160 SCSI for $445 this board also has on-board ATI VGA video. All you need with this board is 2x CPU's + 256MB PC2400 DDR memory + case + power supply == $445 + 2x$160 + $70 + case = $835 + case (reuse your existing disks) Nice to hear it works (and works well, I assume) DAMN NICE !!

Tagged Command Queuing support for IC-35L0?0 ?
Hi, I posted this message on -questions, and since I got no reply I've assumed that it's technical enough to post here on -hackers. Since FBSD 4.3-RELEASE, tagged command queuing is supported for IBM DTLA and DPTA IDE drives. However, the newer Deskstar GXP drives also support TCQ according to IBM's website? Can these newer drives, based on the IC-35L0?0-chipset, also be used with TCQ enabled in FBSD? (? is 2, 4 or 6 depending on whether the drive has 20, 40 or 60 GB capacity).

with TCQ enabled in FBSD? (? is 2, 4 or 6 depending on whether the
drive has 20, 40 or 60 GB capacity).
I think so:
ad0: 58644MB IC35L060AVER07-0 [119150/16/63] at ata0-master tagged
UDMA33
I had to manually add IC35L060AVER07-0 to ata-disk.c (around line 832)
to get FreeBSD to use it though.
...
ad_tagsupported(struct ad_softc *adp)
{
const char *drives[] = {IBM-DPTA, IBM-DTLA, IC35L060AVER07-0,
NULL};
...
This was a month or so though, so someone might have done the right
thing
and figured out how to parse those new IBM product strings to determine
if the drive supports CTQ or not.

I've got one of these :

Good luck, YMMV I think I might have made a local patch to include
my drive.. something like this...
/usr/src/sys/dev/ata/ata-disk.c around line 861
const char *drives[] = {IBM-DPTA, IBM-DTLA, IC35L040AVER07, NULL};
As I said, it didn't work though =(
Steve
P.S. let me know if you suceed in getting it to work, maybe I need a
different motherboard or just to change some settings or something?
