Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am completely new to Linux and am attempting to install Fedora 12 on an HP Pavillion 8766C (Pentium 3 900 mhz with 512 MB ram). I have tried installing from 4 different i386 DVD .iso and 2 Live CD .iso that I burned and the install hangs on each of the discs. I either get a "Anaconda 12.46 Install Exited Abnormally" from the Live CD's or "Boot has failed, sleep forever" from the DVD's. I have also tried the Fedora 12 respin DVD and Ubuntu 9.10 Live CD with similar results. Does anyone have any ideas? I am about to give on the whole thing at this point! The only success I have had is with the Gparted Live CD.
The check sum event is to be commended but also note that some larger live cd's might struggle with 512 Ram. I take it you booted from cd. It is also worth borrowing a known good cd to test the system. A simpler o/s (Xubuntu) might test the hardware for obvious faults,i.e, if it works on that then there's nothing especially wrong.
I told you to check for MD5 errors. Because I had my personal experience with ISO images.
I faced this problem with ISO images of Fedora 11, openSuSE 11.1, openSuSE 11.2, Fedora 11.2
I had downloaded all of them from torrents. It showed me 100% completion. Still i got those MD5 errors. That's the reason i recommended for ISO check ( not CD/DVD check, check ISO before you write them to CD/DVD).
You stated that you got a message that "[b]oot has failed, sleep forever" from the DVD. Prior to displaying that message you should have seen another message describing why the boot had failed. If you could post that message, perhaps we could offer more targeted help.
I think that that error message is only displayed after the installation is finished and you're running from the Initial RAM Filesystem image. If that's true, your DVD was probably correctly downloaded, and the comments (above) should only lead you to running the "verify that DVD" option on the DVD. (It takes a long while to run, but success removes "bad burn" from the list of possibilities.)
Another possibility: Your computer's memory may be flaky. Consider running the memchk option when it's offered. Also, consider replacing your memory chips with, say, a 1 or 2 Gb set. (A 2Gb set would only cost about $40, so it's a fairly cheap upgrade.) The Fedora 12 installation guide suggests 256 Kb as the "recommended" minimum memory for GUI operation, but, in my experience, Fedora (and most other distributions) spend way too much time swapping memory to-and-from the swap disk if you have less than 2Gb real memory. E.g., with 512Kb, you may spend several minutes waiting for your display to "catch up" to your inupt.
Ok, I am now trying to install Fedora 12 (the i386 DVD) on another system (AMD Athlon XP 1400 with 1 gig of ram) and running into a similar error after selecting Install system with basic video driver:
Running anaconda 12.46, the Fedora system installer - please wait.
python: Objects/obmalloc.c:757: PyObject_Malloc: Assertion 'bp != ((void *)0)' failed
install exited abnormally [1/1]
you may safely reboot your system
This time I got used bittorrent so, I think the DVD is good. I did discover a bad piece of ram which I removed. If I choose the first install option I get the same result minus the python error. Any ideas?
My system has an ATI 7000 graphics card and an MSI K7T Turbo motherboard. I was hoping to use the system as a home server with Amahi 5.
I don,t know if it is any help but had a similair error yesterday. Installing fed. 12 to a laptop (hp compaq nc 6220) and although it did install it would not update from the graphics, only via yum. Then it did 1192 updates, mostly to do with changing from 32 bit to 64.
