Is it a Hardware Problem or a Software Problem?

Tuesday, February 1st, 2011

Last night I was working with an older HP laptop and things hit the fan very quickly. I discovered I couldn’t write a file to disk and before I knew it the system had thrown up to a black screen and needed the power cut to reboot. I immediately realized that there was a serious [...]

Booting from CD when a systems BIOS won’t let you

Wednesday, October 18th, 2006

Along the way on my permissions nightmare last night, I made matters worse by changing permissions on a fairly important file. In order to fix that I was going to need to reboot from a boot disk. The only problem was boot floppys typically don’t come with reiserfs support (only the boot cds I’ve found [...]

CDROM drives with yellow exclamation point in Windows XP

Friday, September 1st, 2006

I ran into something I hadn’t yet seen firsthand today. A PC (running Windows XP home) with 2 optical drives (CD-RW and DVD drive). However, neither cd drive showed up in My Computer and both of them had a yellow exclamation point in the device manager listing. Of course, two drives don’t just go bad [...]

Tools of the trade – USB2.0 to IDE & SATA Cable

Friday, September 1st, 2006

Today is the first chance I”ve had to try out my new usb/ ide adapter “in the field”. I have previously used external ide enclosures for either laptop (2.5″) or desktop (3.5″) drives as well as larger (5.5″ cdrom’s) But, it was a bit of a nuisance to have to remove the drive that I [...]

Qemu 0.8.1 speed improvement with -kernel-kqemu and kqemu 1.3.0pre7

Friday, June 9th, 2006

I mentioned the other day revisiting the qemu site to discover new versions of both qemu and the non-redistributable kernel module kqemu (qemu is now at version 0.8.1 and kqemu is at 1.3.0pre7). There’s also a new startup switch -kernel-kqemu which enables FULL virtualization of both kernel and user code. I could feel a difference [...]

Check your hard drive’s temperature in Linux

Friday, January 6th, 2006

I started using this program after frying a hard drive in 6 months. It was on the server and serving up Audio 24/7 and it was sandwiched between a cdrom drive and another hard drive. There was no air flow around the hard drive and subsequently it had a very short and very rough life. [...]

Mandriva 2006 upgrade on Inspiron 8000 laptop saga Part I

Friday, November 25th, 2005

I had a chance today to start the upgrade process for Mandriva 2006 on my laptop (Dell Inspiron 8000). Now, let’s see…. a bit of background. Mandriva (Mandrive/Mandrake) has been my favorite distro since converting to linux several years back (around Mandrake 8.1 or 8.2) I’ve had it running on the laptop since then and [...]

Qemu revisited

Monday, August 15th, 2005

I mentioned Qemu a short while back. I’ve used it in the past for testing linux livecds. After doing the writeup though I was encouraged to look at it again and see if/how much it’s improved since I last got an update. Wow….    Send article as PDF   

qemu for testing linux livecd’s

Tuesday, August 2nd, 2005

I’ve mentioned a few things about linux livecds in the last few days and thought I would also mention a great tool for testing them. QEMU is a program, available for Linux or Microsoft Windows, that allows you to run an operating system within your current desktop. Let me try to clarify, I have my [...]
