This is one of the original alerts on the bad capacitor issue: SEE: http://www.spectrum.ieee.org/WEBONLY/resource/feb03/ncap.html Excerpt from the above URL: "So far, the only motherboard maker to admit to the problem is ABIT Computer Corp. (Taipei), and the only major PC maker to acknowledge being affected is IBM Corp. But the problem is likely to be more widespread. Indeed, those who have repaired the damaged boards say that they have encountered crippled motherboards from Micro-Star International, ASUSTek Computer, Gigabyte Technology, and others." So from the standpoint that Abit has traditionally put out very outstanding products, and from the standpoint that they are just about the only ones that are being honest about the problem, it is lopsided to single them out as being "much much worse." I happen to HAVE an Abit mobo and it's the best I've ever owned. And I've owned a mobo or two, since I used to fabricate for a living. Asus, on the other hand, has traditionally tended to produce mobos with less than 7 slots, sometimes with wierd freako connectors whose standards nobody understands or really cares about. That's my only beef with them. Other than that, their mobos are most of the time the fastest around, and usually they can trash the other ones in the (non-overclocking) vanilla benches, Soyo and Abit included, assuming they don't do overclocking and test the boards vanilla, which is what everybody does anyway. The reason I chose Abit was threefold: One, because of the flexibility of the overclocker bios, which is the most flexible one around for tweaking CPU's. So even if my buddy next door has a soyo or asus, I can STILL outperform his mobo in the quake 3 demo benches cause my Abit allows better tweaking. Two, the mobo had no stupid onboard crap like sound, or lan or anything else that I use cards for because I might want to upgrade that feature later on. Granted, this is not true anymore for anybody when you look at all of the newer boards. Three, the Abit layout usually gives you the maximum amount of slots. They traditionally have had the most beautiful layouts. I've got a Lian Li aluminum case with eight slots available and dammit I want to use at least seven of them. The real man's mobo's used to come with eight slots available. Before I quit here, I will say that Soyo has got some beautiful layouts as well. They are one of the companies that has listened to consumer/overclocker demand and has produced boards with 7 slots. After all, I want to give credit where credit is due.

If you do not mind me butting in here Tom, the A7V uses an onboard Promise ATA100 controller for ide2 and 3 and and an onboard VIA-Apollo ATA66 controller for ide0 and1 so it would be rather difficult for him to get rid of the 100 controller. I have 2 of the retail boards and have been using both for around 2 years or more with no problems, got both prior to the release of 7.2. My drive set-up are similar to his. Machine1 cdrom, dvd, and cdrw on ide0 and 1, 3 hds on ide2 and 3 Machine2 dvd, Creative cdrw on ide0 and 1, 2 hds on ide2 and 3 I have never enabled on any removable drive or even seen any need. Even on machine2 I can burn a 700 mb iso cd in 6 min and still rebuild XFree or play Quake at the same time. The problem Ryan is having could be indicative of an hd problem rather than a cdrw problem. Have not closely followed this thread but, Ryan, have you posted 'hdparm -i or I' for your hds also are they running at the default 16-bit IO mode or have you reset them to 32-bit ?

It's a damn shame 'cause Asus use to be reliable and high performance products. Among the OCr's favorites.

That's the main problem with re-badged drives from a conglomeration of suppliers ... nobody wants to own up to the final product. Anything re-badged should be avoided. Still, a STFW (Google) will probly turn up current firmware info if not a new bios flash for it. Unfortunately, I vaguely remember Ricoh was the transport supplier for Creatives.

That first white pci slot should never be used if there's a card in the pci-1/AGP slot (brown). So hopefully I take it you mean that's empty. If not, move the SB down one slot. It's a good idea to use every other pci slot after that, so you probly need to move the NIC in any case. If that's not clear the brown AGP slot is really the first pci slot (agp is pci). The first white slot, pci-2 should be empty if the 'agp' slot is used. So the SB should be in pci-3, the NIC in pci-5. SB Live! is a good example of bandwidth hog cards on the pci bus, as are the newest nVidia/ATI video cards. Choice is yours, you can't have both. If you want good steady data transfers across the pci/ide bus, they got'a go. If you need surround sound and ridiculously high FPS rates playin games, then expect your drives to suffer the pci/ide degredation in real world activities (hdparm -tT not being one of 'em). 33 mhz only goes so far between so many devices.

I believe as I alluded to before, I think the problem is your controller card. It wasn't clear to me but I believe you've got 2 HDD's, 2 CD drives.

board. The other drives I have are /dev/hda some old shitty cd-rom,
/dev/hdg a maxtor 30 gig running at ATA-100, /dev/hde a quantam 30 gig
ATA-100. You think being less than 2 years old kernel support would have
gone beyond my 12X drive? I've gotten some pretty old, crappy hardware
working w/ new kernels (IDE controller cards and whatnot). I wasn't
using windows as a "hey it works in here why not linux", just that if it
was something physically wrong (i.e. not a driver/config problem) it
should show up every time I use the drive regardless of OS. here is the
output of the hdparm command.

Windoze is not a recommendation for hardware to work on better OS's. 'Works great with Windoze' is most often a derogatory statement about hardware. MOF, that's one explaination I can think of at the moment. Windoze kernels are a joke, Deb's are usually old fashioned yesterday's stuff. Probly older than the kernel you had with 8.2. Could be your hardware is fallin behind current Linux kernels? OTOH, that only somewhat fits your slow tranfer rates tho. The motherboard might. Who makes it, and what chipset? Also mention if it's in a ready made (ie, OEM only), because then it and often it's chipsets are made to that vendors specs or Dell's. What drives are hd[abd] ? might help too. Another possibility is spindle wobble causing eratic signals over IDE. That could account for both slow transfer rates and high cpu usage. At two years old and unknown sources, that becomes a realistic explaination, specially if the transport mechanism was actually made by Ricoh. Have you tried burnin at low speeds (4x) ? Post the output from 'hdparm -v -i /dev/hdc' and maybe somebody'll see somethin I'm runnin out of ideas. -- Tom Brinkman Corpus Christi, Texas Want to buy your Pack or Services from MandrakeSoft?

For some reason, the 9.0 startup scripts turn dma off for optical drives. For this instruction, I will assume your cd-burner is /dev/hdc scsi emulated as /dev/scd0. For your machine, replce the hdc with whatever ata channel your burner is on. Go into the directory /etc/sysconfig and you will see a file called harddisks. Copy this file as root to a file called harddiskhdc. cp harddisks harddiskhdc Edit the new file with your favorit text editor (mines nano) and uncomment the line that says '# USE_DMA=1' so it looks like this USE_DMA=1 and save the file. Since dma is off, it is very likely that hdparm is already installed on your system, but to doublecheck, type rpm -qa | grep -i hdparm if you get no output, you need to install hdparm, so type urpmi hdparm, and follow the instructions. Now when yopu boot up, DMA will be turned back on. Another method would be to remove hdparm completely, which will prevent it from being turned off to begin with. The problem with this approach is that you won't be able to use hdparm to tune your hard drives. urpme hdparm to learn more about hdparm, type man hdparm. - -- Greg -BEGIN PGP SIGNATURE- Version: GnuPG v1.0.7 (GNU/Linux) iD8DBQE+SwhDwDpHP6GALAARAk++AJwO5VVbl/vpUItJyCsVsts9c29NuwCghN0+ //X97CjRQAFrIG3Y8Q+ETsk= =BznK -END PGP SIGNATURE- Want to buy your Pack or Services from MandrakeSoft?

[newbie] Enabling DMA on CD-Writer
Hi, for the life of me I can't figure out how to enable DMA on my CD burner. Burning a CD brings my system to a halt and it takes around 10 minutes to copy data from CD to hd. Any help would be greatly appreciated. Thanks, Ryan Want to buy your Pack or Services from MandrakeSoft? Go to http://www.mandrakestore.com
