I find that unacceptable for a bootsplash file that most will really notice or want. Recall the discussion when you first brought up the bootsplash topic. SeaBIOS as you may have experienced by now only runs for a few hundred milliseconds, and in fact running the VGA BIOS takes most of that time, so a bootsplash would only be visible for maybe a tenth of a second. Suggesting to add artificial delays would not be wise. Furthermore, if there is to be a bootsplash (which I for one don't hold for impossible) then it needs to be generated from the professional project logo (so far there is none) and preferably using scripted free and libre tools. In any case, I think all graphics should be stored outside the source tree, and be an optional addon. See e.g. what we do for the coreboot logo: http://coreboot.org/Logo //Peter

[PATCH 00/10] More vgabios work
by Kevin O'Connor 28 Jan '12

28 Jan '12

This round includes more vgabios porting and refactoring. At the end of this round, all cirrus functions should now be ported - Cirrus vgabios should be feature complete with the lgpl vgabios. -Kevin Kevin O'Connor (10): vgabios: Use stored total memory in cirrus code instead of recalculating. vgabios: Set cwidth/cheight/sstart in vgamode_s for cirrus/bochs. vgabios: Extract out current mode finding into new function. vgabios: Move BDA setting from driver code to common code. vgabios: Add support for vesa get/set window function. vgabios: Add support for vbe get/set line length function. vgabios: Add support for VBE get/set display start function. vgabios: Add VBE power management (10h) stub function. vgabios: Minor - pass display address to stdvga_set_cursor_pos(). vgabios: Move stdvga_set_mode() to stdvgamodes.c. vgasrc/bochsvga.c | 209 +++++++++++++++++++++------------- vgasrc/bochsvga.h | 8 +- vgasrc/clext.c | 317 +++++++++++++++++-------------------------------- vgasrc/clext.h | 8 +- vgasrc/stdvga.c | 183 +++++++++++------------------ vgasrc/stdvga.h | 29 ++--- vgasrc/stdvgaio.c | 1 + vgasrc/stdvgamodes.c | 123 +++++++++++++++++++ vgasrc/vbe.c | 131 ++++++++++++++++++--- vgasrc/vgabios.c | 66 +++++++++-- vgasrc/vgabios.h | 5 +- vgasrc/vgaentry.S | 5 + vgasrc/vgafb.c | 12 +- vgasrc/vgahw.h | 57 +++++++++- 14 files changed, 688 insertions(+), 466 deletions(-) -- 1.7.6.4

I think a "chip" is an ugly and boring shape :\ and the shark while a cool idea is probably difficult to make look nice while still keeping free of significant detail. It's important to keep the shape simple and elegant. The trident is a fun idea but a little bit too pointy, I guess it would also require too much detail to look good and still be really practical. Same for DNA. The gear+waves concept definately wins my vote. Thanks for taking this initiative! //Peter

[RFC PATCH 0/4] vgabios runtime hardware detection
by Gerd Hoffmann 26 Jan '12

26 Jan '12

Hi, This adds runtime hardware detection to vgabios. Survived light (vga text mode) testing. The isa bits are completely untested as qemu -M isapc is foobar atm.

[RFC] vgabios over serial
by Rudolf Marek 26 Jan '12

26 Jan '12

Hi all, I guess it would be not very difficult to add a serial output to VGA BIOS and provide int16 serial input aka integrating the sgabios into seabios? Comments? Thanks Rudolf
