Hi,
I continued to investigate how to reduce the boot time with SeaBIOS
and QEMU when it used with linuxboot_dma.bin (-kernel parameter).
I reached ~12ms with a SeaBIOS configuration (attached) where I
disabled debug output, all Hardware support (except SMM & MTRRs) and I
applied a small patch to d

Hi,
I'm investigating the SeaBIOS booting time, to understand if we can reduce
the boot time in some cases (e.g. legacy hardware is not needed). I think
this
can be interesting also for NEMU developers.
Following this thread (
