There should be settings in your bios main screen for 'Load setup defaults' or 'Load Failsafe defaults' The setup defaults are pretty conservative, but the failsafe is barebones On 10/29/05, Keith Wright <kwright(a)free-comp-shop.com> wrote: > > > From: "John Stoffel" <john(a)stoffel.org> > > > > Bummers, I've been thinking about going the opteron route as well with > > a dual box like this.

Re: [Wlug] Need help: palm -> laptop

by Walt Sawyer

Thanks! That gets me a little bit further. After verifying the device exists, I chmod to get permission for /dev/pilot (which is ln'ed to /dev/ttyUSB0). Now when running the gnome-pilot setup, the palm connects, but the setup app doesn't see it. Again, thanks for your help! It's gotten me a little closer to the goal!

What is the output of "dmesg" It probally created a serial device in /dev/tts/USB0 or something like that.. The prolific USB-Serial adapter just acts like a plain old rs-232 serial port.

Re: [Wlug] System hang woes continue

We have had problems with bulging capacitors. After some research, I have found that many different systems have this issue (Dell, Intel, etc. motherboards). Open the BFH (box from hell) and check the caps. They may be bulging on top or even leaking. This is from an electrolyte formula that was stolen from Japan. Good luck!
