- Since we are on this topic. My full-time job is
- embedded systems design and we are currently developing
- a PCI ATM card.
- What is interesting about PCI mother-boards is that
- many boards do NOT follow PCI2.0 compliance.
- We have tested over 7 different PCI boards and out
- of the 7, 3 boards do not support burst modes (and no there
- was no BIOS setting to enable it).
- 2 that did support burst modes, did so for only 2 or 3 cycles.
- Our NIC card was to do burst for at least 10 cycles.
- I have a PVR, but I don't know if bursting is
- important to it - I know bus mastering is.
- I have not had the chance to put the PVR in our test beds -
- but since my PVR at home is working great, I don't really
- see the need.
- BUT, just to let you know that just because it is a PCI
- mother-board - doesn't not mean they designed to be
- completely 2.0 compliant.
- Most of the boards that were found to be 'less PCI' were
- Taiwan clones - no names.
- But the Triton, Zappa, Endeavor on Dells, Gateways - these
- are the really good boards we have seen.
- This is one reason why Intel has it own mother-boards.
- The requirements of PCI was just too strict for some
- manufactures that Intel was worried that their PCI chipset
- was going on really bad mother-boards.
- But these days, this maybe old news since I
- believe the clones and brandnames do have PCI
- MB design down pat. Unless you buy an old board.
- Just FYI
