No we ran bigger disks than that. INT 0x13 (the BIOS disk interface)
did have a limit of 512MB (my fault actually) but for AIX PS/2 it only
required that the boot block and kernel be located within that range.
Once the kernel was running, it could access as much as the HW would
support and didn't use BIOS for anything.

I bumped the RAM down to 32M and have a 1GB
virtual disk.
For one thing, a gigabyte was an impossibly-large disk for the era.
330MB was vast back then; 520MB was a ceiling even in about 1993/1994
as it required more than the maximum number of cylinders/heads/tracks
that some BIOS INT 0x11 implementations could handle.
I'd try 256MB or so.
The screenshot shows it working on VirtualPC. That's still around and
it's a free download - but you'll have to host it on Windows, and
Windows <= 7 on bare metal, not in a VM.
