Hi,
I am also considering a system with the OPTI chipset and an AMI
bios.
Is anyone familiar with the OPTI chipset?  Any negative or positive
features?  Same for AMI bios (386/486).
I would also appreciate any pointers/recomendations on what to look
for in BIOS's and chipsets for 386's and 486's (potential memory
address conflicts, loading software into high memory, RAM that
can only be used as shadow RAM (how much, if any), etc)
I would also be interested in any experiences with I/O bus speed
and wait state combinations.
Thanks,
John Serafin
