Thread: iPXE, iSCSI and int13
Post: RE: iPXE, iSCSI and int13
| Thanks, I've managed to get the R.o.M. working, so have lovely debug images to play with (with syslog - thanks for adding that!)

Thread: iPXE, iSCSI and int13
Post: RE: iPXE, iSCSI and int13

With that disk removed, it fails in a much... |

Thread: iPXE, iSCSI and int13
Post: RE: iPXE, iSCSI and int13

Post: Few questions about sanhook'ing and BIOS
| I'll start by thanking you all for iPXE. I've only recently discovered it, and it seems pretty awesome. So thanks for that.
