gfxpayload and the multiboot2 header

2011-02-17 Thread Seth Goldberg
Hi, It looks like currently, when a framebuffer tag exists in the multiboot2 header of a mb2 kernel, that resolution is used even when gfxpayload has a different resolution. I think gfxpayload set to a value other than auto should override the value of this tag, as it will give consumers

[multiboot2] Tagged multiboot2 header

2010-01-20 Thread Vladimir 'φ-coder/phcoder' Serbinenko
Current multiboot header has number of problems: - Bitfields. They place a limit on 16 mandatory and 16 optional features. This forces us to carefully consider every flag and sometimes squash marginally related requirements together. - Whether flag is ignorable or not is a part of specification and

Multiboot2 header

2008-11-04 Thread Robert Millan
The Multiboot2 draft says a Multiboot2 header must be included in the OS image. However, our code assumes (in code itself and in comments) that for MB2 this is optional. As a consequence, if you feed GRUB's multiboot loader any ELF, it will attempt to load it. I think this is very conf
