In some configurations, newer versions of QEMU will end up placing the modern interface's BAR4 above 4GB, rendering it inaccessible in a 32-bit build of iPXE. We will currently detect the existence of the modern interface and attempt to use it, but fail at the point of attempting to map the PCI BARs. Fix by ignoring any virtio capabilities that describe an inaccessible PCI BAR, and thereby allowing iPXE to fall back to using the legacy interface if the modern interface's BAR cannot be used.

iPXE network bootloader
iPXE is the leading open source network boot firmware. It provides a full PXE implementation enhanced with additional features such as:
-
boot from a web server via HTTP or HTTPS,
-
boot from an iSCSI, FCoE, or AoE SAN,
-
control the boot process with a script,
You can use iPXE to replace the existing PXE ROM on your network card, or you can chainload into iPXE to obtain the features of iPXE without the hassle of reflashing.
iPXE is free, open-source software licensed under the GNU GPL (with some portions under GPL-compatible licences).
You can download the rolling release binaries (built from the latest commit), or use the most recent stable release.
