Running console command with --keep option -> unable to boot

[Smokey]

Hello, I'm fairly new to iPXE but I hope I can supply you with all the relevant info.

I'm unable to boot any image/kernel I tried if I use the console command with --keep option.
iPXE version used: 1.0.0+ (26050)
I tried both the ipxe.kpxe and undionly.kpxe files.

Tested with:
VMware Workstation 12 Player version 12.5.2 build-4638234 (32-bit VM)
and on real hardware (64-bit) (can post specs if needed).

I'm using dnsmasq on my router (DHCP) and my boot server (Proxy DHCP).

Image used:
Memdisk and memtest from http://ipxe.org/appnote/memtest

When I run console with --keep option before booting an image I get the following error message:

Code:

El Torito BVD sanity check failed.
El Torito boot catalog sanity check failed.
MEMDISK: Image seems to have fractional end cylinder
MEMDISK: Image appears to be truncated

After I press any key to boot, the machine (vm or real hardware) just locks up and I have to hard reset it.

This led me to believe that there was some corruption happening somewhere so I ran the tests at http://ipxe.org/dev/drvtest/md5sum
But to my confusion it passed the tests flawlessly.

iPXE compiled with:

Code:

make bin/{undionly,ipxe}.{,k,kk}pxe EMBED=../boot.ipxe

My scripts:
Embedded boot.ipxe

Code:

#!ipxe

menu.php (I removed the php code and menu for debugging)

Code:

#!ipxe

console --x 800 --y 600 --picture menu.png --keep --left 80 --right 80 --top 60 --bottom 60

initrd files/images/memtest.iso
chain files/images/memdisk iso raw pause

I also tried booting into Windows 7 setup (from http://ipxe.org/howto/winpe)
menu.php

Code:

#!ipxe

console --x 800 --y 600 --picture menu.png --keep --left 80 --right 80 --top 60 --bottom 60

kernel files/windows/wimboot
initrd files/windows/boot/bcd BCD
initrd files/windows/boot/boot.sdi boot.sdi
initrd files/windows/sources/boot.wim boot.wim
boot

It fails with the following error message:

Code:

Bad CPIO magic
FATAL: could not extract initrd files
Press a key to reboot...

And finally I tried gparted live:
menu.php

Code:

#!ipxe

console --x 800 --y 600 --picture menu.png --keep --left 80 --right 80 --top 60 --bottom 60

kernel files/gparted/i386/vmlinuz boot=live config components union=overlay username=user noswap noeject ip= vga=788 fetch=http://192.168.1.2/ipxe/files/gparted/i386/filesystem.squashfs quiet splash
initrd files/gparted/i386/initrd.img
boot

This failed with:

Code:

Initramfs unpacking failed: junk in compressed archive

Everything boots just fine without the --keep option.
Am I missing something here? What am I doing wrong?
I would include screenshots too but attachments are disabled I guess.
Feel free to ask anything, I can post more configs if needed.
