Hi Gene It took me some time to check all the things you've asked. Hope you still remember the case... 1) Compiling SYSLINUX with -j1 didn't help. The first error message I get is about missing header file. I'll try to play a little bit with it to make it compile. 2) The 3-character mode that the version/copyright banner displays is EDD. What determines the it? BIOS? What affect

Hi Gene Thanks again for your help. I'm using SYSLINUX 4.05 distributed by Ubuntu. For debugging I'm using SYSLINUX 6.03 because for some reason if I build SYSLINUX 4.05 from sources I get many compilation errors. SYSLINUX is installed on eMMC storage (along with Linux). I don't see the 3-character mode banner display. How can I check it? So I've added some timing prints to

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

Hi Some time ago I wrote this mailing list about some extra time that it takes for my system to boot and I don't know where it came from.I'm using a custom BIOS which loads at 1 second and now I've found out that it takes for the bootloader and OS an extra 1 second to load when keyboard is disconnected.I got from the BIOS engineer the following explanation and steps to take: In

Hello Everyone I'd like to know what's the best way to measure syslinux functions duration.I know how to measure overall time (from syslinux start), but is there an easy way to break it down? Thanks,Tal

The best is to expose the bootloader in the BIOS as a (readonly) disk drive using standard BIOS or EFI interfaces. -hpa

Hi Does Syslinux support fwrite for fat filesystem?Is it supported for other filesystem?As far as I understand the function exist but isn't fully implemented.Is that correct? I also found this thread that says about the samehttp://www.syslinux.org/archives/2011-August/017093.html Thanks,Tal
