The help talks about BIOS which I know is only on x86.
Does this code include anything that helps a non x86 comp?

The 45 Gig IBM drive hangs the BIOS if I let it autodetect it, so I
turn off autodetection for IDE2 primary where it sits. This is probably
not relevant.

Hi Alan,
This patch makes the 2.4 starfire driver essentially identical to the
version you added to 2.2.19pre. In addition, it also includes Manfred
Spraul's fixes (for problems which, although real, are very unlikely to
matter in real life).
Please apply.
Thanks,

With 2.2.18 I can set using_dma = 1 with hdparm on my Dell Inspiron
8000, I cannot with 2.4.1-ac15, so my HD works about 1/3 the speed with
2.4.1.

A good point. The test results are inconclusive.

Actually, in today's "User Friendly" comic strip (http://www.userfriendly.org)
one of the characters asks exactly that same question.

2.4.1-ac8 worked great, 2.4.1-ac13 and ac14 oops
in IDE initialization. All 3 have ide.2.4.1-p8.all.01172001.patch
applied too. I'll try it without the ide patch today.

Hi,
While trying to compile 2.4.1-ac1[34] I noticed that the following error
message appears sometimes:
make[3]: *** No rule to make target
/home29/ankry/kernel/2.4/linux/drivers/pci/devlist.h', needed by `names.o'.
Stop.
make[3]: Leaving directory /home29/ankry/kernel/2.4/linux/drivers/pci'

Ah, I see. The other CPU does an atomic *pte |= _PAGE_DIRTY, without
checking the present bit. ('scuse me for temporary brain failure).
How about a prag
Oh God. You're right. But who's going to patent the patent on the patent?
