Use The purpose of this call is to return the device and vendor information for the given PCI device. h4. Notes The bit settings passed in R0 specifies the information that must be returned. The string pointers returned point to temporary buffers in the PCI Manager's workspace so you should take a local copy of the strings as they will be invalidated by the next call. This call is analogous to [[Podule_ReadInfo]], for a given R3. h4. See also * [[Podule_ReadInfo]] * [[PCI_ReadInfo Request]] * [[Using PCI Devices]]
