Can not boot RHEL 7.3 by using iPXE

[MultimediaMan]

This is a known issue.

You can "solve" the problem (most of the time) by doing the following:

DD a 16MB or 32MB file:

Code:

dd if=/dev/urandom of=32MB.bin bs=32MB count=1

Then place the file in the Webserver or TFTP directory...

Place the following line in your boot script:

Code:

initrd http://path.to.file/32MB.bin

Some things can get tricky... the order in which they are downloaded can affect things; in general I will download the initrd(s) and any *.bin file before the kernel:

Code:

initrd http://path.to.file/initrd
initrd http://path.to.file/32MB.bin
chain http://path.to.file/vmlinuz initrd=initrd

Yes, you are just filling some parts of the memory with random characters, but if it works...

This scheme works most of the time...YMMV.
