576-MB DOC reports as Millennium?

[Bill Burgess]

Doc2000.c can't seem to handle the new 576-MB DoC's.

The docprobe.c driver (version 1.30) reports them as
Millenniums, but then doc2000.c (version 1.46) fails
to access the mfr or id using Millennium-oriented calls;
these come back 0xff or 0.  If I force the ChipID to be
a 2000, docprobe doesn't even get past the initial toggle
test.  Also like a blank Millennium, there is no 0x55aa
signature at the base address, only 0xffff.

The 576's have NOT been formatted with DFORMAT
or anything else, they came raw.  However what I am
attempting is so low-level, the formatting should be
irrelevant -- shouldn't it??

I am not actually using Linux, but have incorporated
the drivers into a low-level custom system based on
a 68K.  The drivers have worked beautifully for months.
Even now I can swap an 8-MB or a 288-MB DOC2000
into the socket and they work fine.  So I don't think
it's my platform that's suddenly gone off.

If the solution is not obvious or quick I will have
to buy some 288's very soon, which will hurt as I have
already bought the 576's :-<  Help!

Cheers & thanks!
