I did download Mr. Miller&rsq= uo;s image. It would not boot at all until I replaced the files that you me= ntion, but the kernel in that image locks up after detecting the fourth cor= e of the CPU. However, from that failure I learned that those files, (start= _cd.elf, start4cd.elf, fixup_cd.dat, fixup4cd.dat) are necessary for the Pi= to boot, and that those with the bootcode.bin and presumably, but it doesn= ’t seem to matter whether I use bcm2711-rpi-4-b.dtb or bcm2711-rpi-40= 0.dtb - the dtbs are vital to the process. - and that all those files simpl= y need to be copied into the fat partition/boot directory.

So I burned another image (actually many, trying different SD ca= rds, and different configurations, older kernels, etc) and replaced all the= files I’ve mentioned with the ones from https://github.com/raspberrypi/firmware/tree/= master/boot (hopefully that’s where I should get them). My m= ost recent iteration just has the single error repeated:

sdhc: read error intr 2008002 stat 1fff0000

=
This occurs many times. In the middle of these errors is 

/dev/sdM0: BCM SD Host Controller 02 Version 10

then the error repeats itself over 50 times before prin= ting out the lines
/dev/sdM0/data
bootargs is (tcp, tls= , il, local!device)[]

At no time during this pro= cess is the keyboard or mouse responsive. Though the mouse icon did become = visible during the boot process. 

I am hopi= ng I am wrong, but I am thinking there is some sort of driver issue. At the= very least, checking what media there is to mount, or reading the SD card.= And then possibly for other things, but the former could be gumming up the= works for everything else.
