Function RTT_BIOS_Rescan

This function can be used to search for PCI devices added to the system after program start:

void RTT_BIOS_Rescan(BYTE Bus);

Parameters

Bus

PCI bus number to rescan. If zero is specified, all PCI busses will be rescanned.

RTTarget-32 caches data about installed PCI devices. If a scan has revealed that no PCI device is present at a particular bus/device index, subsequent scans for the same bus/device will not actually access the PCI bus again. To delete such cached information and to make added devices visible, a call to this function is required.
