New Revision: 31131
URL: http://svn.reactos.org/svn/reactos?rev=31131&view=rev
Log:
- Pass ARC Hardware Tree in SetupLDR too.
- Zero-initialize memory from the Hardware Heap, just to be sure.
- Don't set the Version/Key/Affinity when creating the system node, let the caller do
this.
- Fix the way components were added in the tree, it was busted.
- Enable setting of component information for the APM and ACPI component nodes. This was
#if'ed out because it crashed the kernel while PnP was getting bus information for
ATAPI/SCSIPORT, since the nodes had no component data. Add some component data to remove
the crash, and then enable component information.
- The Real Mode IRQ Routing Table is a Peripheral Class, not a System Class.
- Enable the code to create component nodes for each PCI Bus, it was #if'ed out ages
ago.
- Don't create any component data for the PCI BIOS, it doesn't have any.
- Create component data for the first PCI Bus component node based on the
PCI_REGISTRY_INFO strucutre.
- Fix the way the BIOS Hard disk Peripheral nodes are created.
- Always create the DiskController node with floppy disk information, but don't do
actual floppy detection if no floppies are there.
- Fix flags for Floppy Peripheral nodes.
- Fix vector for Floppy Peripheral node.
- Set component information for each BIOS hard disk peripheral node.
- Fix component information for Serial Peripherals, they were being created on the Serial
Controller node instead.
- Set empty component information for the system node.
- TODO: Setup ACPI and APM Bios descriptor information.
- TODO: Setup ROM BIOS Block descriptor information.
