Hi
I had read some part of the Mindshare book about PCI system architecture. But I do not really understand what happen during PC start-up. In order to read the Vendor ID and Device ID, the data transaction also need to follow the timing diagram as shown in below ?
I do not have the device driver yet, but i want the PC able to detects the attached PCI device. Is by detecting the Vendor ID and Device ID are well enough for PC to know there is a PCI device plugged in and assign some memory space for the device ? (I will do scanning to obtain the assigned memory space later.)
Thanks and best wishes,
