| + | - gPXE is an open source PXE stack and provides UNDI services. gPXE cannot be used as an option ROM without a native driver. | ||
| + | - UNDI is slow because gPXE must switch CPU modes when calling it. | ||
| + | - UNDI ROMs can be buggy or violate the PXE specification. Native drivers are known to work with gPXE and can be fixed if there is a bug since they are part of the gPXE codebase. | ||
| + | - Enabling the network boot ROM in the BIOS is not always possible or desirable. | ||
