69030 Databook
These two bits specify the longest-possible amount of time that this graphics controller will
take in decoding an address and asserting DEVSEL#. These two bits always return a value
of 01, indicating a medium-length timing.
This bit applies only to PCI Bus masters. Since this graphics controller never functions as
a PCI Bus master, this bit always returns a value of 0 when read.
This bit always returns a value of 1 when read, indicating that this graphics controller is
capable of fast back-to-back transactions that are not in the same segment.
This bit always returns a value of 0 when read, indicating that this graphics controller does
not provide features that are definable by the end-user.
This bit always returns a value of 1 when read, indicating that this graphics controller can
be used with PCI at a bus speed up to 66MHz.
This graphics controller is compatible with the AGP bus as a device capable of frame-based
AGP transfers, only, but it is NOT compatible with PCI-66 (the 66MHz version of PCI first
described in revision 2.1 of the PCI specification from the PCI SIG).
The setting of this bit has NO bearing on AGP compatibility -- this bit is entirely ignored by
AGP device configuration firmware.
Each of these bits always return a value of 0 when read.
