Here is my keys: ... <pci#cc_0600> <pci#cc_0604> <pci#ven_8086&dev_244e> <pci#ven_8086&dev_27b8> <pci#ven_8086&dev_27c0> <pci#ven_8086&dev_27d0> <pci#ven_8086&dev_27da> <pci#ven_8086&dev_27df> <pci#ven_8086&dev_27e0> <pci#ven_8086&dev_27e2> <pci#ven_9005&dev_0080&subsys_e2a09005> <primary_ide_channel> ...

Can I remove them and add the new ones what you wrote me?

Let the one already in place, and just add the missing ones. Existing ones won't cause troubles.

Do I type in the registy entries under [1] and [2] exactly using copy paste?

Yup.

I'll check those vendor IDs above.

How can I check the ones what Qemu using? (IDE/SATA/SCSI/Virtio)

One easy way to find out is to use lspci -nn in a Linux host running Qemu with your target configuration. For instance, for the IDE bus, you'll get something like: 00:01.1 IDE interface [0101]: Intel Corporation 82371SB PIIX3 IDE [Natoma/Triton II] [8086:7010] -- Pierre Schweitzer <pierre@reactos.org> System & Network Administrator Senior Kernel Developer ReactOS Deutschland e.V.
