30 AugUpdate BIOS by building FreeDOS CD

Posted by admin in New
No Comments

BIOS updates on Linux can be a problem.  There are a very few BIOSes for which there are Linux utilities, and some for which the motherboard manufacturer provides ISOs, but for many, the only method provided is a DOS utility.  For these, the excellent Sean Reifschneider posted a method:

http://www.tummy.com/journals/entries/jafo_20080920_234755

which has just one buglet.  At the end of the third line of code:

-b isolinux/isolinux.bin

there needs to be an addition; it needs to look like this:

-b isolinux/isolinux.bin \

Hopefully I can obtain permission to repost a fuller set of instructions :-)

10 JulOptimize compilations on 64-bit AMD and Intel CPUs

The best I've found so far for generic use, is this:
-O3 -march=opteron -mtune=amdfam10 -m64 -mfpmath=sse -mcrc32 -ffast-math -fomit-frame-pointer
If you are using a latest-generation AMD64 CPU, made by AMD, the following is recommended:
-O3 -march=amdfam10 -m64 -mfpmath=sse -mcrc32 -ffast-math -fomit-frame-pointer
For many applications, especially graphics and math-oriented, the -ffast-math item will need to be removed.  -O3 may have to be replaced with -O2 for some code, too.

This:http://linkchecker.sourceforge.net/works very well.  Its only issue is it doesn't understand mailto links, it thinks those are all bad.

In current distributions, there is a new nVidia driver, called "Nouveau".  Many nVidia video chipsets, even motherboard chipsets less than a year old, won't work under Nouveau.  For these, a procedure has been identified:http://linuxsoftwareblog.com/?p=232Curiously, I found that the video mode setting on the end of the kernel line is very important.

Lots of weird package install problems in Fedora, can be fixed by rebuilding the 'yum' database, thusly:

Here is an interesting project:http://code.google.com/p/ppss/producing a shell script, which makes it quite easy to use multiple cores at once for many command-line operations, e.g., file format conversions and the like.
