...#39;t see the 3-character mode banner display. How can I check it? So I've added some timing prints to SYSLINUX 6.03 and got the following results: bootloader start 1179.140 ms before loadfile 1180.320 ms after loadfile 1454.250 ms before bios_do_shuffle_and_boot 1465.795 ms kernl_start (main.c) 2298.054 ms The Linux image size is around 10 MByte. You can see that the time that it takes to read it is around 280 ms. It is slow compared to reading it from Linux but it doesn't what take the vast boot time. You can see that the vast boot t...

Measuring boot time
Hi Gene Thanks for your reply.I'm trying to breakdown overall system boot time and to understand each component duration. My linux image is a ~10 MB bzImage file with the rootfs cpio'ed inside. I also have 2 BIOS images:- some general purpose BIOS - a custom BIOS which loads real quick I'm using TSC to measure time. I'm not sure it's the best way (I've read about CPU's
