How to configure the Android bootloader so that it can boot from the network? Where do you get this information from?

Question

Android

In general, I took the settings from the hornbeam, which was in the image, and inserted it into my bootloader, which is on pxe, it turned out like this:

bootloader config

ui vesamenu.c32                  
PROMPT 0
menu background background.jpg
menu title 123

LABEL bootlocal
   menu label Boot from first HDD
   kernel chain.c32
   append hd0 0
   timeout 120
label livem
  menu label Live CD - ^Run Android-x86 without installation
  kernel /kernel
  append initrd=/initrd.img root=/dev/ram0 androidboot.hardware=android_x86 video=-16 quiet SRC= DATA=

label vesa
  menu label Live CD - ^VESA mode
  kernel /kernel
  append initrd=/initrd.img root=/dev/ram0 androidboot.hardware=android_x86 video=-16 quiet nomodeset vga=788 SRC= DATA=

label debug
  menu label Live CD - ^Debug mode
  kernel /kernel
  append initrd=/initrd.img root=/dev/ram0 androidboot.hardware=android_x86 video=-16 vga=788 DEBUG=2 SRC= DATA=

label install
  menu label Installation - ^Install Android-x86 to harddisk
  kernel /kernel
  append initrd=/initrd.img root=/dev/ram0 androidboot.hardware=android_x86 video=-16 INSTALL=1 DEBUG=
 TEXT HELP
The system will boot after the time is up
 ENDTEXT

In general, the bootloader is loaded, I make a choice, and this is what it says:
early console in decompress kernel
decompressing linux... parsing elf... done.
detecting android-x86.............................................. .........
And so on ad infinitum. How to fix it? And / or what to read on this topic useful?
