(UEFI) Dell XPS 15z L511z modded BIOS - and HOWTO

[follow_me]

Ah ok - there is the source code for OVMF in the tree, which I'll try to build externally to QEMU in the next few days so we can look to integrating it into the BIOS for testing. Will report back soon.

@jkbuha - with what compiler do you build now ?
Can you please report then what image size will be when compiled.
I'm using GCC 4.8.1 - and size of the rusulting OVMF image is x2 of it should be

[jkbuha]

I'm using two compilers: VS2012 for the Win build and gcc 4.8 for Clover on Mac.

On a related note there would appear to be some interesting changes in the ed2k source (and Clover's corresponding changes) to OVMF. Might be worth you compiling Clover (as it natively builds the ed2k framework first) instead?

@follow_me - not sure if you were waiting on my reply for the OVMF size; it is 1MB (1048576 bytes) in size.

Any luck your end on the compilation side?

@jkbuha - There is no problem with compilation itself. I'm just worrying about result image size I get, because we are limited in space. I thought , may be I should change toolchain

I see. Have you tried 4.9.1? I'm contributing on a linux-related sourcetree (rockbox) and whilst the recommended compiler is gcc 4.4.2 I use the latest gcc and have optimised compilations of ~30% less in size and ~5% faster. Just my $0.02...

Can I just flash the WPH file form the OP with winflash? I found this thread that makes it seem a little simpler (http://forum.notebookreview.com/dell-xps...-more.html), but I would like to be certain. I have the xps 15z l511z with the i7

[jkbuha]

Yes that thread has been written by myself as well but the more recent WPH is on this board (I haven't updated that post in almost two years).

FWIW I also have the L511z with i7.

Hey
Is the new update suitable for XPS L502x (corei7 2630) ?
UPDATE 20/09/2014: Added new experimental ROM with the following changes:
- Updated Intel VBIOS to latest version v2170 (vanilla); full support for all L511z ports
- Updated Intel Microcode to latest version 0x29; works perfect on Win7/8.1/OSX
- Replaced PXE Boot Manager with the excellent PLOP v5.0 Boot Manager (thanks for the tip @Florin9doi)

Thanks

[jkbuha]

No it's not. As per the first line: Only for L511z.

@kasar should be preparing a v7 BIOS for the L502x shortly.

Havn't heard of Kasar in a long time, I'll try to contact him to make it happen for L502x
Thanks
