iPXE boot to Windows writing back to boot device

[mdevey]

Thanks for this, using the setup with SameGuyAsBefore.

Compiled the fakewrite branch. No luck still writes to cf.

For giggles tried the following but nothing changed.

wimboot/src/int.c

Code:

//other int 13h codes that looked vaguely write'ish
                case 0x0b:
                case 0x03:
                case 0x05:
                case 0x06:
                case 0x07:
                case 0x45:
                case INT13_EXTENDED_WRITE:
                        int13_extended_write ( params );
                        break;

Verified I used a modified wimboot by altering read to fail, and window gives a nice error message.

ipxe/win7 combo may just expose a bug in our system. Would welcome any suggested parts of ipxe I could alter to help track it down?

Thanks for your time.
