OpenGL problem with MatLAB

I had this problem long before and at the time nobody could understand what the problem was but now many people are aware that it is MatLAB which ruins the OpenGL settings.

The thing is, if you are still playing games on your PC and if those games require OpenGL you may face difficulties if you are also using MatLAB on that very computer of yours. MatLAB interfere with OpenGL code and makes the games give nonsense errors. You can not originate the problem since they don't have any connection with display. If you have such trouble, just hit Ctrl-Alt-Del and check wether any Matlab.exe is running. Although you are not using MatLab at that time, Matlab.exe can be in running processes list and that is your enemy! Force it to shut down and play your game in peace!

How to install WinNT on (logical) Secondary drive

If you are reading this, you are aware of the fact that Windows NT only lets you install it on the primary active partition. If you are using two HDD, then it is simple. Just remove the first HDD and it should install without any problems on the second drive which is now primary. Okay, what if the second HDD, on which you are trying to install WinNT is not a physical drive but a logical one? The solution is again simple. Just restart your computer and enter BIOS settings. From the BIOS settings go to the Boot Up Sequence menu and select a drive letter which does not belong to your primary partition like, "D, CDRom, A". Although so such drive exists, BIOS and OS thinks that the logical drive (partition) is now primary. You know what to do next...

Libretto 110CT XP Display Resolution

So you have managed to install Windows XP on your beloved Libretto 110CT, congratulations! But, although Windows XP has recognized your display driver precisely, the resolution is not correct. When the resolution is 800x600, you use virtual desktop which is extremely annoying! You want to switch back to your old 800x480 resolution and live happily ever after...

That is an extremely simple task to do. First right click on an empty area on your desktop and click on properties. From the window appeared click on Settings tab and then click on Advanced.

Casio PB-2000C and ROM Cards

This is by far the best pocket computer ever manufactured. The only setback is, it is slow. However, this doesn't mask the good points of this device in any possible way.

PB-2000C comes with C interpreter known as K&R C. K and R stands for the first letters of the names who in fact invented the C programming language. This version of C may lack some of the exciting points of ANSI C but it is tremendously more exciting to use the very first C on such a pocket computer.

Besides C there are some other programming languages available for PB-2000C and one of them is BASIC. The BASIC version on PB-2000C is different then the one which available on its' close relative PB-1000. The main difference is that there are no commands like TIME$ or DATE$. Besides some commands like LINE is different as DRAW. BASIC ROM is a little faster than C.

There is another ROM which is CASL for which I will add information later.

The most exciting ROM among all is PASCAL ROM. This is developed by Hans Larsson which by all means humiliated Casio engineers. This ROM gives you wings over PB-2000C and you have the power to code things which is not possible with any other ROM module. Better memory management, faster programs and many additional functions make this ROM shine brighter.

HP 200LX and Memory

HP 200LX is a 80186 based pocket computer which has MS-DOS 5.0 readily installed. This MS-DOS 5.0 is not complete and needs the original disks to be completed. However, this doesn't concern the memory issues which I am going to discuss here.

In order to use your favorite Dos software on 200LX you need more space than it offers to you by default. The maximum standard memory you can find on these computers is 4MB. The DOS takes away 640KB and you are left with the rest. No compiler like Turbo C++ can fit in that space so you need a solution.

At this point CF cards come to the rescue. 200LX has a standard PCMCIA slot. Since CF cards can be used with PCMCIA adapters, it is easy to connect them to the PCMCIA slot of 200LX. However, it can support up to 128MB and these CF cards can rarely be found these days. I have used Kingston 128MB CF card and I know that it is very slow, specially when you enter DIR command for the first time. Therefore a SUNDISK or a CF card which has 64KB memory can be more suitable.

How to install XP using a 40GB HDD on Libretto 110CT

The problem with 110CT is that it doesn't recognize HDD over 8GB. You get around this obstacle by first installing windows XP on that 40GB drive on another computer. When you leave the HDD format as FAT32 and then install that HDD on 110CT, you can start with your installation on 110CT by using a boot disc which is generated by any MS OS starting from Windows 95. You should install Windows XP on Libretto again and the easiest way to do that is to copy Windows XP CD on that 40GB HDD while it was still connected to the other computer. You boot your Libretto from FDD and switch to HDD and start the installation by entering SETUP from the command line. This way, you will not need to deal with EZBios or similar software to make your Libretto recognize your large capacity drive.
