PCI board not working in some mother boards?

["William Benner" <William_Benner@email.msn.com>]

Hi all,

I am wondering if anyone can help. We have been distributing a PCI board
that uses the Cypress CY7C09449PV-AC chip (Formerly the AnchorChips AN3042Q
"Comem LITE") since 1999 with great results. Recently we have a client who
informs us that when he places our PCI board into some mother boards, the
system will not boot.

For this client, the list of working mother boards are:

DFI        CB61             Intel Chips (old)
Elitegroup K7VTA3           VIA KT333(VT8367),(VT8233A) Chips(new)
Gigabyte   GA-7VRXP         VIA KT333 AGPset(new)
Gigabyte   GA-7VR           VIA KT333 AGPset(new)
Gigabyte   GA-71XEH         VIA KT133/KT133E AGPset(old)
Gigabyte   GA-7ZXE          VIA KT133A AGPset(old)


For this client, the list of non-working mother boards are:
Gigabyte   GA-7DX+          AMD 761/VIA 686B
ASUS       A7S333/PA/UAY    SIS745
MSI        MS-6561          SIS745

Does anyone have any ideas as to what might be going on here? Could there be
some 3V/5V issues here?

Best regards,
