I am missing any help/any utility to enable/disable the internal CPU cache of the Cyrix Cx486DX2 (in fact it is a clone named "It's ST 486DX2-80") in a reliable way. I've tested several 486DLC tools, but they do not work or do not even start (because it's of course not a 486DLC), the 5x86 utilities …

@RiP - it's a long time ago, but meanwhile I got the same problem. Did you added the 2 Diodes and the resistor, and if, what resistor value have you taken (e.g. 270 ohms... but I would start with the highest to be considered value always) ?

What about Cyrix (ST and TI built it, too) Cx486DX2 ? So far, at least this CPU (Cx486DX2-66 and Cx486DX2-80) have a lot of additional features, e.g. Write Back Cache (which was implemented for Intel 486DX CPUs later, with the 486DX4-100, also with the AMD 486DX-133). As far as I can see, some other …

Thanks. "Pentium Pro and later (Pentium II and higher)" is usually called "686", "586" means usually Pentium (1) and above.

Did not find any hint about when the CMOVA (for example) instruction was introduced - does it exist since Pentium IV or later (Core Solo/Duo) or none of them, instead ... ?

Unbelievable, but your archive.org Link does work, regardless of the file size (usually such big ISO files aren't captured). Don't know the difference between the file without "October Update" and your referenced file, but it's definitely worth a try.

The old Watchguard Fireboxes (Firebox FB10, FB100) uses well known PC mainboards like ASUS P55TP4N. The successor of the first Fireboxes, Watchguard Firebox FB II and FB III are using the same technology, but smaller, not well known PC mainboards. Transforming the FB 10 and FB100 Boxes into a retro …

Just for completeness. I tried also to use a Rage 128 AGP card later, some problems occured also, but I was able to fix it. These VIA 4in1 chipset driver versions are really different, they behave different, they have a different compatibility to each card/manufacturer. Finally I tried 4in1 443v, …

The problem is not DirectX version related, it seems hardware related, because (see my 1st post in this thread) I was trying a lot (tried Windows ME with build-in DirectX 7, too). Apollo Pro 133 is unfortunately not exactly the same (memory controller is definitely different), and M64 support ( …

Finally I gave up. I removed this shitty ATI All-in-Wonder 128 Pro card and re-inserted my ATI Xpert 98 (Rage Pro) card. Guess what happened... the sound card immediately worked. So I will sell this card, not compatible with my PC/mainboard/whatsoever.

Figured out later: I disabled USB Port (did not used it on this board) and also the 2nd serial port. Now I can see IRQ 5 is assigned, but this time ctcm shows a "ERROR: Bad Resource data checksum" two times, then exit without success. This is absolutely weird.

Meanwhile I've replaced the SB16 Vibra with a SB PCI 64. My Idiot-PC BIOS assigns always IRQ 9 at boot time. And I can't change it. Seems to be a fault of the mainboard, I was setting the IRQ settings to manual and all of the available entries were set to PCI, also because I have no ISA card in the …

Hmm me thinks it a driver issue, The All-in-Wonder used diff chipset and had TV Tuner AND diff driver iirc which means multi IRQ's... You need to fully uninstall the drivers to ATI 98 and not just set the Windows video to VGA. I learned to hate ATI cards back in the day because of driver issues. …
