If you don't mind your mouse skipping around a bit with some lag, go ahead with the vetra systems converter. Also keep in mind that they have 3 such converters. All convert PS/2 signals to RS-232 signals and each unit requires a very specific mouse driver that you will need to hunt down. The driver …

I have an IBM 5x86-133 system setup with a PCI ATI Rage 128 VR card. The display driver works fine in Win9x using the IBM 5x86-133. In WinNT 4.0 and W2K, I get BSOD upon reboot after installing the drivers. I tried every driver revision I could find. Normally, I would conclude that this graphic …

Seems reasonable considering the time put in and the continuing time required to solder.

I only put the battery in. How much do you think these can go for? After shipping and such, a brand new RTC from Maxim is around $22 USD.

I have only seen it whereby you can use DB9 RS-232 and RS-485 serial devices on a USB port, not the other way around. If you have a link to someone who has made a converter that lets you use USB mice on a computer's RS-232 serial port, I would be interested.

I few minutes in google should provide plenty of answers. This topic has been beaten to death. 1) PCI PS/2 cards are really USB cards with a PS/2 converter on it. You need to install the USB drivers for this to work. It will not work out-of-the-box with DOS. You will need to figure out how to get …

I have put the DS12887 into my IBM 5x86-133 system and will report back in a month as to how well it is keeping time. For the short few hours I have tested it thus far, the unit properly saves BIOS settings and keeps time.

If you are trying to install Win98 on another computer and move the HDD back to the Presario, you might want to install Win98 on a Cyrix 6x86- or Cyrix 5x86-based computer then transfer the HDD over.

Sleepless nights of online searching. This is how I found the Cx5530 drivers for my ECS P5GX-M motherboard. Russian and eastern European FTP sites seem to be great resources for old drivers.

The drivers disk should have NT4 drivers. Those may work with W2K. For Win9x, try using a FAT, not FAT32, partition. If it is BGA, I suspect 180 MHz or less.

You need to locate the Cyrix "companion" chipset drivers. It is either the Cx5510, 5520, or 5530. Start with locating the Compaq drivers disc. I only have the drivers for the 5530. It contains drivers for UDMA disc access, VGA, and sound. What speed processor do you got in there? Is it a BGA or …

So its safe to assume the AM5X86@160 edges the Cyrix 5x86@120 for gaming? I found it suprising that the AMD scored higher than the Cyrix in Quake I would think its also safe to assume the AMD would score better for most games in that case. With both run on the Biostar board, X5-160 15.1 fps in …

That X5-160 in your VLB board has really nice memory throughput results - slightly better than in PCI-based 486 boards. Your Cyrix 5x86-120 seems to be configured nicely now, however I do not understand your slow L1 cache speed before you set the Cyrix register bits. It is as if you had L1 set to …

Have one. It requires the USB 2.0 drivers from the OS. Those PS/2 ports are converted USB ports.

I surely overlooked this thread somehow. Aside from the MMX-enabled chips, it seems Cyrix did not make any improvements whereby these 4 benchmarks could benefit from. Two tests even indicate some performance loss. I wonder if Cyrix had to sacrifice a feature for stability at higher frequency chips. …

Vetz, no, I do not believe so. I seem to recall FSB not considerably affecting the Speedsys score for the same internal CPU frequency. Or do you mean a POD at 125 MHz? If a POD at 125 MHz, then it will surely have a higher Speedsys score. Are you able to POST at 125 MHz? Artex, test results indicate …
