I just installed centos on a Dell that used to have 2 internal disks, but I removed one just before the install. Now when I boot it, it stops and outputs a message complaining about the missing disk and I have to hit F1 to get it to continue booting. Is there some bios setting that is causing this? Obviously, I'd like it to just forget about the missing disk and go ahead and boot with just one, the one that was present when I installed the OS. I want to RTFM, but I'm not really certain where to start, it's outside my comfort zone. mahalo, Dave -------------- next part -------------- An HTML attachment was scrubbed...

I am not sure how to deal with this. It seems to be a Dell-specific BIOS hack of some sort (and a *dumb* one at that).> > mahalo, > Dave > > MIME-Version: 1.0 > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos > >-- Robert Heller -- 978-544-6933 Deepwoods Software -- Download the Model Railroad System http://www.deepsoft.com/ -- Binaries for Linux and MS-Windows heller at deepsoft.com -- http://www.deepsoft.com/ModelRailroadSystem/
This is not a "Dell-specific BIOS hack". Dear child, ask your folks about PCs. I think it was only this decade that PCs would actually boot *without* a keyboard. EVERY PC EVER MADE before would not. Nah! Every BIOS since I remember (at least from 1990) had a choice on the first page, Standard BIOS Setup. "Halt on all errors, Halt on keyboard/video errors, Halt on no errors". At least these three were always present. Of course the default is always "Halt on all errors". Unless you modify the settings on purpose, that's what happens.

Is it a PowerEdge server? Some sort of embedded RAID controller (PowerEdge and Precision workstations both have those)? More information required to fully answer. A Dimension desktop shouldn't have this issue, but a PowerEdge or Precision with PERC or CERC set up will have this issue, and you need to access the controller's setup to tell it the other disk is gone.

(tongue firmly in cheek....). There are Dell keyboards like that, too. Macs have been that way for years, too.

With SATA cables that don't have latches still common, it is all too easy for a cable to fall out (have seen it happen on a Precision 690, and it was a SAS drive not SATA; also have seen it happen with a whitebox with a 3ware 9550 RAID controller, where a SATA cable vibrated loose). I'd rather the box stop booting and then tell me about it than boot anyway. And I like SATA cables with latches..... I personally would prefer the box to stop and halt boot if the intrusion switch had latched; but only with LOM, DRAC, serial redirect, or IPMI in place to remote console.
