[gentoo-user] DMA and ide-scsi

2003-06-25 Thread Richard Revis
Hi, I have found references in several places which state that you should be able to use hdparm to enable dma on ide-scsi devices, however when I enable ide-scsi the /dev/hdX entry (in this case /dev/hdd) for it vanishes and hdparm refuses to work when pointed at the SCSI entry. Any clues as to

Hi ppl, Anyone know how to set (and check), the various IDE features, such as DMA, for cd drives that are being emulated by the ide-scsi generic driver? Normally i'd use hdparm on the /dev/ide/blahblah... But once they are being governed by the ide-scsi driver, they appear in

Thomas I don't think that will work as those proc locations should not exist Thomas if you have not loaded those devices using the IDE module. Of course they are. If your motherboard has an IDE bus, the proc interface will be there, no matter if you load the ide-scsi modules. That's the beauty ;)

[...] Mal May I then assume, that hdparm is essentially unnecessary, aside from Mal changing the DMA mode and changing power saving settings? I don't know. I do know that, for all the things I use hdparm, I can use the /proc interface; but I don't know if hdparm can do something that can't be
