The BIOS on the original IBM PC totally made it easy to code a homebrew bare metal OS which could access all the peripherals. These BIOS calls exists today in i7 based motherboards allowing OS's coded in the 80's to still (mostly) function on a modern Motherboard, its biggest fault was being 16 bit which meant all newer OS's needed to write there own once they switched to 32/64 bit mode.
The BIOS layer made the PC easier. I find it frustrating that almost every new SOC I get, even from the same manufacturer requires me to re-code all my IO routines.
If a common BIOS existed across the ARM/x86 which emulated the simpleness of the original BIOS concept and not the API hell you usually get now, there would be a lot more adventurers in homebrew OS's
