The so called Integrated PC Server (IPCS), formerly known as File Server I/O-Processor, or later as Integrated xSeries Server is a family of add-on cards for certain AS/400 models.

These were offered as means to integrate Windows (and later, Linux) based workloads into the same physical hardware. The cards came with a dedicated INTeL-CPU and RAM, as well as usual peripheral ports. Optical and tape storage could be shared by either OS/400 or the OS running on the IPCS. Disk storage is virtualised as disk image files in the IFS of OS/400. Depending on model, PCI-slots on the backplane can be used solely by the IPCS.

Through the addition of expansion towers or PCI Cages to the bigger systems, more than just one PCI based IPCS can be managed by OS/400.

The integration is extended to OS/400 automatically replicate newly created user profiles, or password changes to the running windows instance. This integration is very tight and scripted at install time, using a second virtual hard disk to load more drivers before the OS kernel is launched. Early Linux support required the use of an USB floppy drive to add needed proprietary IBM drivers for the virtual disk files, to make an install of Linux possible at all. This tight integration makes it very hard to nearly impossible to install and run unsupported guest OS in a generic way.

Earlier OS/400 releases provided support for OS/2, Novell Netware and Windows NT. V4R5 dropped Netware support but added support for Windows 2000. V5 started support for selected versions of SuSe Linux Enterprise Server, and Red Hat Linux.
