also, not all computers have uefi or bios.

It would be really hard to use a computer with no firmware at all, but
it could be just an OS loader.

You are getting it wrong. There are firmwares that are neither BIOS or
UEFI, there are others. And other types of computers besides "the PC".

To be more clear: a MAC has neither BIOS nor UEFI. It has a firmware
with a different name.

intel macs use uefi.
powerpc macs used open firmware.
68k macs had nothing.

Nothing configurable, but surely it has firmware :-)

At least enough to load the boot code from disk and display some error
code if not.

68k macs booted directly from rom, which contained a substantial
portion of mac os, aka the toolbox. the startup code was just another
part, which ran only once.


Even my old Apple II+ booted from Rom there were 6 Roms which I believe
were also the Apple-soft operating system, if I remember correctly,
That's 40 years ago but I remember making some changes to the machine
code and burning new Roms on my homemade Rom Blaster.

patching the mac rom was *very* easy once the system was loaded and
done entirely in software, either on a per-app basis or systemwide for
all apps and the system itself.

the intent was so that apple could easily fix bugs in a system update
rather than needing to replace roms. third party developers took full
advantage of being able to patch the os and added all sorts of new
functionality, nearly all useful although some was more for amusement.

other than pata, no.

So all those chips on your SATA drive are NOT integrated?

they are, but that doesn't make a sata drive an ide drive.

Then, IDE is something other than Integrated Drive Electronics. Perhaps
you could say what it is?

it isn't.

Isn't what? Isn't anything?

"nothing" sounds like those ROM-less microcomputers from the seventies,
that wouldn't do anything until you manually entered the bootloader with
toggle switches.

those were minicomputers, such as a pdp-8 or pdp-11, dating back to the
1960s.

it's nothing at all like early macs or various other computers of that
era, none of which had front panel switches, except the altair and
imsai.

OK. Then how does it apply to PATA but not to SATA?
