Klaidonis 0 Posted February 21, 2020 Share Posted February 21, 2020 I am making a minimal Clover build for the fastest boot possible with the boot6 file in legacy mode. While looking at the preboot.log, I noticed that there is a line without explanation (at 0:892). Apparently, whatever it is, the execution time of it is close to 2 seconds, more than 55% of the total logged boot time in the current configuration. This does not change whether I use USB 2 or USB 3 port. Is there a way to eliminate or speed up the above? Also, is there anything else you can suggest to improve the performance based on the below log file? Which moment in the boot process corresponds to the start time in preboot.log? The last thing I would like to understand is the delay/timeout after the boot6 file has loaded, and the number 6 disappears from the screen. For about 2 seconds or slightly less, I can press any key, and then it will enter the BIOS-like interface from the boot6 file. Without further knowledge, it seems like those 2 seconds are just delay time, and only after that is CLOVERX64.efi actually started, which, I presume, is approximately when the preboot.log timer starts. So, if the aforementioned is correct, can I get rid of this delay as well? Note that I am using the boot1f32 file to chain-load boot6, which does not include the initial 2-second wait period for a keypress. === preboot.log === 0:100 0:100 MemLog inited, TSC freq: 2394459554 0:100 0:000 CPU was calibrated with ACPI PM Timer 0:100 0:000 LegacyRegion2: Chipset/proc: 0x0A048086 0:100 0:000 Next Generation Core processors (PAM 0x80-0x86) 0:100 0:000 Test PAM1=(0x41=90, 0x5a=90, 0x81=11, 0x91=00) at chipset 0A048086 0:100 0:000 , Install = Success 0:112 0:012 BiosVideoDriverBindingStart!

apianti 1,246 Posted February 21, 2020 Share Posted February 21, 2020 No, I doubt you'll get very much faster. This is basically the equivalent of turning on your computer again, it has to build a bunch of stuff to work in EFI from the legacy BIOS interfaces. They are slow and you won't have very fast boot times with legacy. Link to post Share on other sites
Slice 6,843 Posted February 21, 2020 Share Posted February 21, 2020 2 seconds delay is made for choose between boot6 or boot7 waiting while you press a digit "6" or "7". It is bootsector boot1f32alt You may choose boot1f32 without this delay in the Clover Installer. Link to post Share on other sites

There is no way to speed up what is happening there, it is not building the binaries, it is building the firmware structure for EFI by wrapping it around BIOS interfaces, it basically has to load and initialize drivers for all your hardware based on those (which is terrible and slow but the only way to interact with some stuff on legacy machines). The interfaces are what is slow which is why legacy booting is much slower than UEFI. You can't get any faster because that's as fast as legacy can get. Think of it like a little mini OS booting, your computer is basically booting twice, once in legacy mode, and then once in EFI mode. The two second timeout to choose boot6 or boot7 happens before the log is ever initialized so you would never see that in the log, as that is happening in boot6 or boot7, lol.

Klaidonis 0 Posted February 22, 2020 Author Share Posted February 22, 2020 Thanks for the clarification! What you said about boot6 and boot7, I already knew. So, does it all mean that CLOVERX64.efi is executed immediately after the moment when number 6 disappears from the screen, although you can press any key for about 2 seconds more, thus switching to the BIOS-like interface contained in the boot6 file?
