[PXE Network Boot Server]

The other files:

ldlinux.c32
libcom32.c32
libutil.c32

Are also in the "/usr/share/syslinux/" directory.

The PXE boot process gets the "tftp server" from the DHCP request.  It then uses "tftp" to download a 32-bot DOS program that then downloads and displays the menu. Menu's can be nested (by referencing a menu rather than a kernel).  The location of the kernel and ramdisk are relative to the directory specified in the configuration of the TFTP server.  The value of 1000 in the time out is 1 second do you need to multiply the number of seconds by 1000 for the time-out vaule.  Also the "kernel" and "append" are on there own lines and each must not span a line (that means two lines one for each).

Another issue is that the standard Gentoo "genkernel" does not produce a initial ram disk which brings up the network to mount an NFS shared filesystem. I had to edit the "init" script to bring up the network and had to add in the dhcp client as well when I created a PXE based gentoo imager (about 7 years ago).

 

[Ugly Fonts Firefox]

Also the site is setting the font sizes in "pixels" rather than points.  A point (pt) is 1/72 of an inch.  It is a old printer sizing.  While a pixel (px) is depend on the density of the pixies.  In the really old days pixels were 70/inch on the CRT type displays.  Today they range from 70/inch to 144/inch (like my 1080p 15 inch screen) to even more per inch for 2K or 4k device.  My cell phone for example is 1080p display but it is only about 0.4 the physical high and physical width of my laptop putting the pixels/per inch in the 400 to 500 per inch range.
