PCI phased out? (Announce)

Do you have experiences with some PCI-E to PCI converters or somewhere I saw a PCI-E chip with parallel output interface that was simply programmed by few registers. There should be something similar for implementing MMIO but I never come closer to it.

AFAIK new revision will be upgraded within a month and then it will take some time for manufacturers to replace it. Yes you can live with other SATA port but I wouldn't like the feeling that something is rotting in the chip...

And does your 64bit application got some significant benefit from 64bit platform, e.g. in data throughput or it's just ~2x bigger binary working +-few % the same as 32bit?

Maybe, but different chip generations of one vendor are usually not compatible so when they release new generation chip (e.g. GeForce 7xxx -> 8xxx) you'll have to upgrade driver on your live CD. So it's better to have one simple standard and keep it in future.

I was thinking about live CDs on mini 8cm disk. There's about 200MB. I think it's better to stuff it with usefull utilities then fill it entirely with different drivers levanig space only for bares hell.

I think there are still some (maybe obscure) single 1.44 or 2.88 floppu mini distros.

Hm here you say that you would find usefull "more fully featured VESA" but from your previous write I got feeling that you want to kill ALL the legacy stuff, little bit inconsistent. Of course I understand there's now difference between my wishes and reality and I cannot do much more with it (except supportinig some obscure openHW/openFW projects).

But C64/Amiga never aspired to became wide and long computer standard as PC. The PC compatible was set this standard and now it's leaving it. So I think it's time for raneming the whole architecture...

Yes maybe it would was better that MSDOS was forgotten when 386 was introduced (before I got PC) and e.g. OS/2 was spreaded instead it. We would bring us much brighter future. But it didn't happened so and there spreaded a lot of DOS apps that I like. Maybe as you said the sharp break would be bettes. Even intel probably planned it with itanium IA64 which missing x86 (or poorly emulated) but it didn't become standard.

I know. I was also thinking about something like that, make openHW PC (probably FPGA based) supporting all good standards of DOS day. But as my student time has ended I will never have enough time to realize it. Maybe some chinese guys will come with such portable emulating DOS games/demos engine :)
