Re: [PATCH 2.6.13-rc6] dcdbas: add Dell Systems Management Base Driver with sysfs support
Please download libsmbios 0.10.0-beta1 and send the "dumpCmos" output from your machine. Please send it to the libsmbios devel mailing list. >From that output, I can tell you if this token is available on that machine. If that token is available, then yes, you can set that feature. libsmbios can be obtained from http://linux.dell.com/libsmbios/main/ dumpCmos is part of "make minimal", so you don't need any other libs present to compile. It is found under bins/output/ after compile. (alternatively, install the libs and bins rpms) -- Michael On Thu, 2005-08-25 at 14:44 +0100, David Greaves wrote: > > I have a Dell SC420 > Is there a way (based around this patch) to allow users to enable and > set the auto-power-on BIOS feature? > (ie tell the BIOS to power on at 3:40am, power the system down, watch > it > power up at 3:40am) > > Normally I'd use 'nvram-wakeup' but it dosen't understand the Dell > BIOS. > > If so what I'd _like_ to do is send a patch to nvram-wakeup that tests > for this capability and uses it if it's there. > > David > - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/

I have a Dell SC420 Is there a way (based around this patch) to allow users to enable and set the auto-power-on BIOS feature? (ie tell the BIOS to power on at 3:40am, power the system down, watch it power up at 3:40am) Normally I'd use 'nvram-wakeup' but it dosen't understand the Dell BIOS. If so what I'd _like_ to do is send a patch to nvram-wakeup that tests for this capability and uses it if it's there.
