found a Pentium 4 2.8Ghz 400Mhz Northwood (SL7EY) first time i see a p4 400Mhz clocked so high, according to Cpu world this one is rare and the 3Ghz version is basically paper launch it came out of an IBM Baby Desktop with i865g and no AGP Weren't these common, not rare? I thought the P4 2.8GHz …

Hm, so it would mean that F85227N eSPI to LPC bridge provides LDRQ for DMA? That seems to be the case, based on what the Asrock person said. I have problems with this though after some research. How the bridges were explained to me by my friend, is that the lpc bus basically gets clamped into an …

I inquiried Fintek for datasheets. Unlikely you will get a response other than them asking about the product you're designing. Also even if you did get the documents, they would be confidential, so you wouldn't be able to talk about them. I know someone that gets sample chips all the time, and they …

These chips do support LDRQ# on their side (LPC). It's the host (CPU/chipset) that needs to support it somehow. Modern CPUs/chipsets don't support that anymore. eSPI uses even fewer pins than LPC and by itself no ISA-like DMA, and can be driven with even faster clocks. Some chipsets, at least with …

eSPI to LPC chips exist, but I don't think there exists one that would somehow emulate LPC DMA. The NCT6796D chip on the Asrock boards I talked about claim it Supports LDRQ#(LPC DMA) and SERIRQ(Serial IRQ) (datasheet link) The F85226A chip from Fintek also claims it Supports LDRQ#(LPC DMA), SERIRQ( …

This might not be possible, but I found a few chips on modern motherboards that claim eSPI still supports LPC 1.1 via bridge chips such as the ECE1200 or F85227N eSPI to LPC chips. The ECE1200 eSPI to LPC chip is only like 4 bucks, and could be a pathway to supporting dISApointment with any …
