Alot of older machines cannot address a 40gb drive, they just freakout.
The bios on machines usually have a ide cut off depending on their age.

Common bios limitations.



504 meg
2 gb
4 gb
8 gb
30gb
and 137gb.


Real fun working with older machines now a days.

(And here's a good article on why there is a problem.)

And the 30gb limit exists on a lot of p2 machines.

Using MAME to fix real arcade machines is priceless. It really shows that the purpose of MAME is to preserve arcade life.   ;D

No, for two reasons.  For the limitations mentioned below, I'm sure, and because you don't partition the disks.  You write the image directly to the drive.

And, if you want to really dig into the wayback machine, 32 meg. :)

Actually, 32 meg was a partition limitation, not a bios limitation.
(Computer bios didn't know about hard drives, it was up to the controller)


remember this?

debug

g=c800:5

or for the strange RLL controllers

g=c800:ccc
