Subject:	SCOUG-Help: speaking of the PCI sniffer . . . .

Content Type: text/plain

F.Y.I., I ran across this later (1.x) edition of PCI,
now in 32-bit form. You can easily find it with
Google, though there is no OS/2 port yet. VK may have
one in due course. In the meantime, here is the most
relevant (for us) portion of the ReadMe.

" ■ OS/2 Warp

Firstly, I don't own or have access to OS/2, so the
the following is only
heresay as reported by OS/2 users; but I believe it to
be accurate. PCI works
OK under OS/2 - it just runs in a DOS box like any
other legacy DOS
application.

Apparently an OS/2 specific port of PCI is now
available, which is not written
or supported by me! It is my program, heavily modified
to be a native OS/2
console application, as well as a few minor
behavioural changes to suit the
author's personal taste. The ported versions carry
the letters VK on the end
of the version number - I.E. Version 0.45ßVK.

For questions regarding the *vk version, please mail
Veit.Kannegieser@gmx.de
His website has an even longer URL than mine; the
English version of which
seems to be:
http://www-user.tu-cottbus.de/~kannegv/index_e.htm

I encourage OS/2 users to try both versions. Veit's
port usually lags a
version number or two behind mine, and I've had odd
reports of his version
crashing where mine doesn't, however there's no reason
not to use Veit's
version instead of mine if it works better for you.

Generally, OS/2's AGP support in OS/2 is minimal, at
best. Whilst there is
nothing stopping AGP working in OS/2, very few drivers
bother to support it at
all, or only partially (i.e. basic PCI level support,
or 1x speed only). You
have to ask yourself if you need AGP under OS/2 anyhow
- unless you're somehow
doing 3D gaming, animation or texture mapping, AGP
really won't make much of a
difference. Plain old PCI-speed is more than good
enough for general 2D work.

OS/2 supports PCI interrupt sharing, but many OS/2
drivers (about half) don't.
Thus, it's usually a requirement that there be no
shared IRQ's in an OS/2
system. This is getting increasingly awkward to
achieve on modern chipsets and
notebooks, further restricting OS/2's continued
growth. "

I don't know if those last two paragraphs constitute a
dis, of sorts, but they're not particularly
encouraging. Especially when you consider all the
work Serenity, Innotek, and others have been putting
in to stave off obsolescence.
