Re: ICH2-M IDE controller
It seems Benjamin Close wrote: Hi All, Is anyone looking at supporting the Intel ICH2-M IDE controller? Yes. This controller is basically the same as the ICH2 controller except it has extra powermanagment features as it's the for portable computers (hence the M=mobile). I'm currently using the attached patch which runs flawlessly on my laptop. However, I'm just an amature code hacker and hence can't guarentee I haven't missed something between the chipsets. This patch seems about right, I have something very semilar in one of my trees here, just I havn't had a chance to test it yet, but if this works for you I guess I have my case :) The other question I have is why in ata-dma.c is there the fall through to the ICH chipset? It seems to prevent any drive actually using ATA100/UDMA5 features. The fallthrough is just for modes less than ATA100 which is setup the same way as on the ICH therefore the same code.. -Sren To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
Re: ICH2-M IDE controller
I think there are a few chips like that, that cannot do ATA100, but only vaguely remember hearing about it. - Original Message - From: "Benjamin Close" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Saturday, March 24, 2001 6:49 PM Subject: ICH2-M IDE controller Hi All, Is anyone looking at supporting the Intel ICH2-M IDE controller?
