What to do when SIP does not link with Scilab 4.1.2

If you see the error message below when trying to activate SIP Toolbox in SCILAB...

Do this:

chdir(ImageMagickPath);
link('CORE_RL_magick_.dll');


Then reclick the "Toolboxes" button.

DDR1, DDR2, SDRAM? How to determine a PC's memory when upgrading

I have a desktop i bought in 2004. It's still working fine but I wanted to upgrade its 256 MB memory. But how do I know which type of RAM to buy? Without a manual, I took a look at the label of the existing RAM - it says there 256MB DDR 266MHz. But what is the maximum amount of memory I can insert?

I found this very useful application which can tell me what my RAM types are and more:

Note that each RAM slot has a maximum memory capacity and the motherboard has a total maximum capacity. It doesn't pay to insert 3 1 GB DDR's in a motherboard with a maximum 2GB capacity.

Upgrading Without a Recovery Disk

My Lenovo 3000 C100 did not come with any Windows XP CD. Instead, the OS is embedded in the harddrive. I do not like this arrangement. First, it takes up precious space in the harddrive. Second, should the harddrive get useless, how do I upgrade?

And so with only 40GB (32 GB only with 8GB reserved by XP for Rapid Restore) my laptop quickly lost space. I bought an 80GB disk (the website says my laptop model can only accomodate up to 100GB and there was no such size in the market) and agonized whether I should install Mandriva or Ubuntu instead.

The decision to remain in XP was arrived at when I realized I would not be able to program in Matlab since my Matlab license is for Windows. Oh well, I can always dual boot. Scilab is fine but would need more improvements in image processing.

Fortunately, I found that it is possible to make a Windows Installer from such embedded OS. The original link seems no longer active. But here's a tip : In google, type How to Fresh Install Windows XP Without a Recovery CD. I thank profusely the one who figured this out.
