Yeah, fine. Even so, we're talking about distances over one meter. Last
time I checked, the CPUs on my BP6 are not one meter apart.

Oh - go read the Slot 1 spec in the Intel data book - it's
a synchronous bus - all the CPUS on an SMP backplane are
running on a single clock and clock skew between them
has to be way below 1 clock for it to work.. As someone else
pointed out all you have to worry about is offsets of the clocks
from different clocks coming out of reset at different times
(via the APIC protocol- one gets to be the master). I'd guess that
an OS would do some fancy footwork at boot time getting the CPUs to
agree
on TSC values - they wouldn't have tobe exact just so as you
can get the TSC skew down below the APIC message time (in clocks)
you'd be OK
EV6 (ie Athlon) on the other hand runs source-synchronous individual
CPUs can have arbitrary clock skews WRT each other (but again who cares
if the OS get the TSCs to within something less than the APIC latency)

AMD k6-2 or k6-3 cpus can be in a dual cpu config?
Any one running red hat linux 6.2 in a dual system? IS there any

BP6 with 6.2. RH6.x comes with stock SMP kernels, and normally the
installation detects this OK and defaults to the right one. But I prefer
to do my own kernels, so never used RH's much. I'm sure they are OK with
Alan Cox, etc on the payroll. Other than the kernel, I can't think of
anything else that requires a special SMP config.

Hal is talking about the Abit BP6 - a dual PPGA-370 (!) Celeron MoBo.
Even though I own the same board running stable SMP with RH 6.1 still,
as well as Caldera 2.3 and several SuSEs, I don't know if I should
recommend that board - not so much because of the numerous reports
of system lockups after several days uptime (the reason of which
still uncertain), BUT more due to the fact that the newer Celerons
come for the FC-PGA socket, and you'll soon can't buy '370 CPUs any
more.
Complain to Intel about them arbitrarily changing CPU interfaces every
few months (in order to keep the MoBo market - and the user - running
?),
but it is a fact.
Despite that, the Abit BP6 still IS a comparatively cheap entry point
into SMP IMHO - even if another limitation of it comes to my mind :
it has got only 3 SDRAM DIMM sockets, thus allowing "only" 768 MB RAM
(of which I've already implemented 640, so the "end" in sight...).
Altogether, I'd state that the BP6 with a flexible BIOS setup, espec.
for tuning FSB speed etc., is more interesting to experimenters (and
overclockers), rather than for someone willing to set up a stable
production SMP server.

Yes, I didn't intentionally recommend it for various reasons. I fought
the lockups for many moons. I finally got it stable with the QQ BIOS, but
it has been a hair raising experience. I still feel like I am walking on
ice, though have not had a lockup since late Feb. But also the Celeron
changes. The HPT ATA/66 has been a source of problems for some as well.

Patch the kernel. See linux-ide.org. Or try 2.4.x kernel. Some code base

Sounds like a standard QIC-24 tape, which aren't too standard
anymore. Most drives that can read this type of tape are ancient
history (being anything over 5 years in the computer world is pretty
much ancient history..).
Things that seem to have some lasting value lately have been 4mm DAT
and DLT's, with new formats being around (AIT, Mammoth, etc, that are
too soon to tell about lasting value). Best yet would be to burn it
into CD, they are so common now-a-days, the format should be around
for quite some time.
Dysan made media, and didn't really define any standards.

If I am correct. this tape is the same as a DC600A from
3M/Imation. I know for a fact that my old crufty Wangtek 5150es reads
them VERY well, In fact, my drive PREFERS them over the DC6150s I have
bought from Maxwell (ugh! Maxwell Data tapes seem to SUCK!) I can read
it for you and xfer it to a DC2120 mini-tape if you need. (or if I had
the HD space I could xfer it to a DC6250 (you supply the blanks, I am
broke).
While we are on the tape and quality issues. which types of
data cartridges seem to work the best? the Worst? My drive seems to
like the following
DC600A, DC6150, DC6250 (according to wangtek support, it can do this
one). My little beastie floppy based IOMEGA Ditto 800 (also on same
macnine) does DC2120, TR1, Dc2120EX or is it XL? (the big honkers that
look like 8tracks (no insults, I happen to listen to 8tracks).
I tried the Maxells as I got a good deal for them, they
suck!i tapes are full of read errors! (yes, my heads are clean!) Cans
someone tell me how to reformat these? I mean LOW-LEVEL format and
verify!
the 3Ms I have that are over 20 years old read/write without errors!
How are Verbatum DC600A or DC6250 or DC2120s? Should I stick with
Imation tapes?
