The other way to do it is to remove IO.SYS and MSDOS.SYS (or IBMBIO.COM

If memory serves, it will tell give you the non-system disk error
message a couple of times before dumping you to ROM BASIC.

Are you
sure the AT has ROM BASIC? I don't remember that at all.
Yes I am 100% sure my AT has ROM BASIC (that's the machine I am typing
this on, BTW). It's the later (8MHz) model, so I assume the older ones
had it too, certainly the manuals I have imply that.
It's pretty hard to get to in most AT ystems because it'll boot from the
floppy or hard drives rather than run ROM BASIC. But I suspect you could
pull the disk cotnroller card and it'll go into BASIC.
