my HP ProBook 5420s supports custom boot logo but I can't get it working.
It has UEFI (not BIOS), custom boot logo option is on and I have placed a 1366x768 (native.. also tried 1024x768 as guide told so) bitmap to HP_TOOLS\Hewlett-Packard\Logo\Hplogo.bmp according to HP UEFI guide I have found: http://h10032.www1.hp.com/ctg/Manual/c01564727.pdf

1UEFI is not a type of BIOS - it's an alternative/replacement for BIOS firmware. – paradroid – 2010-11-28T23:55:37.243
On older bios's they have to be an uncompressed bitmap image of a certain file size or less, even then some images will not load into the memory space provided for custom images, it can take some trial and error. Can you post the guide? – Moab – 2010-11-29T00:00:40.173
@paradroid, in reality it is a bios, just nothing like the original IBM version, it is still referred to as a bios in all documentation from Dell, HP etc...http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=us&docname=c01443329
– Moab – 2010-11-29T00:07:09.653@Moab: I would imagine they have done that to make user-support less confusing. – paradroid – 2010-11-29T00:56:04.303
1@paradroid They are both firmware, they both run code from the MBR, they both hand off hardware to the OS, they are basically the same thing, just different terminology and some improved technology. Lets not get too picky now. – Moab – 2010-11-29T03:03:36.270
@Moab: I have posted link to the guide in my question – OndroNR – 2010-11-29T10:56:52.107
Ooops, sorry, is it an uncompressed bitmat you are using? – Moab – 2010-11-29T21:24:33.060
it has 3MB.. solid regions.. I think it is uncompressed bitmap – OndroNR – 2010-11-30T20:16:35.673
