the "chip" on Intel Pro/100 VE is just a PHY, not an Ethernet controller. PHY is the analog frontend https://en.wikipedia.org/wiki/Media-independent_interface MAC (actual Ethernet controller) must be on the motherboard for the CNR card to function. Looking at wiki and pinouts.ru first version of …

That's cool. ATX and probably PCI. The only problem is absence of new CPU and SIMM sockets, chipsets and all of that stuff unless somebody stashed some 😀

Don't see much use of it tbh. More like 'I can do it' approach. There is DOSBox exisiting already where you can concentrate your effort on emulation of a particular hardware that is not supported yet and any fix/improvement becomes available for any DOS game you want to run. While recompilation will …

The CNR card typically has the analog interface such as the PHY while the controller is in the chipsets. This does not imply that the built-in Ethernet controller is dumb and push everything into CPU. The built-in Ethernet controllers in Intel/VIA/NVIDIA chipsets have much better offloading …

There is only jumper 12, no sign of JP16 (like they reserved space for it but did not add on 2.1). Agree, they look even more like burnt, not corroded. Maybe even burnt inside, because they are not connected outside. This one cost me just $2 with $2 delivery, so I'm going to buy a new one. Do you …

@majestyk thank you for your answer. There is no JP16 on my board, it appeared on rev. 2.4 and mine is 2.1 I've just noticed two strange looking pins on the second chip. According to datasheet these are pins 70 and 65 (VCC0 and VCC) but I don't seem any connection on the first chip to these pins as …

Hi there. I have the similar issues and don't want to create another topic for that. I have ASUS P/I-55TP4XE motherboard (rev 2.1). Here is the manual: https://pcrebuilding.altervista.org/9/download/55d5c664cee64_asus_mb_pi_p55tp4xe.pdf It has 256K of cache already in chips but I wanted to be cool …

I wanted to buy just the desktop case, but when the seller showed me what's inside I've decided to buy the whole PC. It's Asus P/I-P55TP4XE with that rare Asus Media Port and I decided to make it the base of my Pentium 1 build. The mobo didn't pass the boot test, so I extracted all the chips, washed …

I was looking for a good desktop AT case for one of my builds and bought 'non-empty' one for some extra payment. Seems like I've got the Asus P/I-P55TP4XE. I had to google for Asus MediaBus - haven't even seen it before. And COAST cache for sure. Suddenly it became an unexpected candidate for my P1 …

I could have bought two Voodoo 2 cards for 85 dollars each if I were quicker. I've got only one, the second one disappeared and now we have only one proposal per Ukraine costing something like $200. Things become more and more expensive. The rule of thumb to me - if you see something - buy it …

Got some new stuff. First of all, Philips LMS CM206 2x CD-ROM + CM260 controller for it. Never seen that interface before That's LMSI, not LMS. I have Pro Audio Spectrum 16 in its LMSI variant. I was so enviously looking on a similar one on eBay. That would be so authentic but way too expensive :)
