My PowerBook165 has 8MB of RAM, I don't remember that PB165 has
returned "out of memory".

Yes, I think so.

I think your 1.2 MB kernel is very small already.
I made 1320KB sized kernel for '030s one year ago.

This kernel is just for the booting test with small amount of RAM.
It can boot up with 5MB of RAM (onBoard 4MB + 1MB) on LCIII+ (with
optional FPU). Avail memory is 2496KB.

Yes, indeed :)
    LC 475 can accept up to 132MB (onBoard 4MB + 128MB SIMM).

Macintosh SE or Classic has MC68000 CPU. Some accelerators such as
MicroMac PerformerPro ('030/32MHz + FPU) are available for them, so
they are ready to go NetBSD world (Macintosh Plus has non ADB keyboard),
but those 68000 Macs still have the limitation = "max. RAM is 4MB" !
I'd like to see NetBSD is running on SE :)

Can anyone boot NetBSD with 4MB RAM?

I put my old conf file. It makes 1320KB sized kernel which boot up
with 4MB RAM, doesn't with 5MB.

I think there are some unnecessary options on it, anyway.

This is my new conf file for a FPU-less '030 Macintosh.
