Actually, USB is ok with PAE. I recently updated the PAE configs to not disable PAE and at work we've run PAE kernels with USB enabled for a few years now on 6.x w/o any problems. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

If you remove "device usb", you will also need to remove uhci, ohci, ehci, umass, ukbd, etc. etc. etc... from your config as well. You do not need to disable USB support in the BIOS; the kernel will simply state that it sees devices on the PCI bus but lacks a driver to attach to them. This will not harm anything. -- | Jeremy Chadwickjdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.

Right now, I am just commenting them out, now I know what people mean when they say they are running a trimmed/clean kernel. I did see one potential issue... # USB support device uhci# UHCI PCI->USB interface device ohci# OHCI PCI->USB interface device ehci# EHCI PCI->USB interface (USB 2.0) device usb # USB Bus (required) I see all of these with nodevice lines in the PAE file.

You can usually do 'man 4 ' to see what devices it supports. In this case, adv(4) supports mostly ancient Advansys SCSI host adapters.

Do you mean, in this > case, remove 'nodevice adv' from the PAE file? If so, I don't know what > that supports :/ Yeah, I don't think anyone's really explaining this very well to you, so I'll try a different approach: Certain FreeBSD drivers do not work in PAE mode. The drivers which don't work are listed in the /sys/i386/conf/PAE file. They're prefixed by the word "nodevice", which tells the kernel config reader "DO NOT build this device, because it won't work". You will need to take the "nodevice" lines from /sys/i386/conf/PAE and put them into your kernel config file. (There are alternative methods such as using "include" directives and so on, but I'm trying to keep this explanation simple.)

Excuse the ignorance, I'm more a programmer than system guy. How do I purge a driver, or know which driver to look for, from the config and know what the driver supports?

Some drivers don't work with PAE (see all the 'nodevice' lines in /sys/i386/conf/PAE). You'll need to purge those drivers from your config.

You will get a BTX fault in 7.0 if your CPU does not support 64-bit "long mode" (i.e., amd64). You can check to see if your CPU does support it by looking in the 'AMD features' line of 'dmesg' from an i386 kernel and seeing if you have a 'LM' feature. If you don't, your CPU only supports i386. -- John Baldwin ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
