only one of the two drives to high density, but that shouldn't affect

spare parts bin.
I'm curious about how the chip update appears on the II. Does this
system
now show up as a IIx? My understanding is that the upgrade kit included
a new set of ROM chips that include the same bits as the ones from the
IIx.
Hopefully there's a logical way to detect this upgrade, but it would be
interesting to know if the update changes the gestalt ID.
Under Mac 7.1 it gets definitively recognized as Mac II. I definitively
have a SWIM, since one of my two floppies reads HD disks, I checked
Penguin says my gestalt is 6, Mac II
A clue for the MacII is the 68020 CPU + FPU + MMU, AFAIK the only apple
machine with these specs.
I tried to boot a current 2.6.18 kernel just for fun, it goes past the
letter screen and dumps stack after recognizing the TOBY frame buffer
card and attempting to init it.

PS: I didn't use this mac since many months, it first stasrted up, but
then refusedfurther boots with the sad mac sound and no video output.
REmoving components trying to isolate the problem didn't help. When I
put al back together with no luck, a last attempt made it boot. Any
ideas? I see no visible damage on the motherboard, the batteries still
have some juice left...
