Re: quick start in new motherboards

Peter and Ted,

In a message posted elsewhere by a  hardware designer I read:

"On some TYAN motherboard with AMIBIOS and Intel i810/815 chipset
or on some newest VIA boards with AWARD
after PowerON I see in the BIOS table no cards exept my. So
I run pci test soft and see that all cards on PCI Bus
phisicaly present, but part of their PCI Configuration space is failed.
If we see in PCI standard - motherboard must wait about 2 seconds
for flashing PCI Config Space of PCI cards.
But newest motherboard after 2 second boots Windows."

In all my PCI boards, for bus interfacing, I use FPGAs with configuaration
devices, what have I to expect?
I haven't met this problem yet.

Thanks for your last feed-back!

Marco
