Overclocking Celerons especially the 366s need a great deal of mental
preparation, a great sense of selectivity and is quite an art not
suitable for those who don't understand it. You also need a
cooperative and knowledgeable dealer too, as some dealers don't take
kindly to picky questions (e.g. what week is your Celerons made and
where?) and I really don't think it's wise to telegraph the dealer that
your motives is to overclock it that high, as many dealers take a dim
view on that.
It assumes many things, which are quite specific:
1.) You need a programmable voltage motherboard, which only Abit has,
and no other brand has.
2.) or You need a programmable voltage slotket, which only Asus or MSI
has. I have been using one to overclock a Celeron to 500.
3.) Malaysian Celerons week 14-25.
4.) You need approximately 2.3 or 2.4v for burn in at the start,
settling to 2.0 to 2.2v after burn in.
5.) Don't forget a generous cooling unit. I use the same large "cube"
for both my K6-III 450 and Celeron @ 550.
You simply do not grab a Celeron out of random, put it on any
motherboard out of the shelf, and expect this sort of overclocking (to
550) to just work right off. You can forget about Slot 1 Celeron 366s.
In my case, I simply tracked a dealer who had run out of Celeron stock,
so he won't have old inventory, and assume any new shipment he has would
be of new production. Malaysian Celerons are much more common in the
Far East so it's a given the new inventory is much more likely to be
Malaysian.
This process is quite a bit more picky than when I overclocked a Cel
266, which you almost have no concern as to when and where it was
produced and on what motherboard you need to use it on (no voltage
upping needed.) With the Cel 300a, some voltage upping is needed, but
it's not as picky as to the date and time of production and as to where,
and a good percentage may work right off with no voltage upping.
When Intel introduces Celeron 500s, which is soon, one can also expect
Intel will end up using the best Celeron yields for this, and it might
cut back on the overclocking success percentage once again, as it did
with earlier Celerons, so this is just a short window of opportunity
once again.

I've worked on quite a few laptops now, and my favorite points to
look at (you need to do some research if they matter for you) are:
- hot swappable external mouse (most mice are PS/2, but gpm allows
combo serial external and on-board PS/2 easily)
- APM with suspend to memory and suspend to disk (the latter far more
useful)
- video card supports not only 8bpp, but also 16 or 24/32 in XFree,
and ideally also 640*480, 800*600 and of course 1024*768. The low
res ones are useful if you ever need to present something and "they"
only have the old types of projectors that do lowres stuff (vga/svga).
Well, i could list more, and in fact, i recently wrote them up in *my*
ideal laptop, but this is of course a rather subjective choice. If you
care to look, check out

Subject: Zoom 56K PCI Modem
Date: Sun, 11 Jul 1999 02:35:39 GMT
Hiya group,
I just installed Mandrake linux 6.0 and have a question (well several
actually, but I'll try to keep them in the right groups). My modem
detects itself as a com port in windows and when I install the drivers
it puts itself on com port 4 with irq 11. I cant get it to respond to
KPPP through any of the options in that program. I'm just wondering
if any of you guys know how to get Linux to recognize this modem. I
thought about going out and buying another modem that will install on
com1 or 2 but want to try this first. I'm fairly sure this isn't a
"winmodem" so please help me if you can. Thanks in advance.

Date: Sun, 11 Jul 1999 02:08:07 GMT
Help
I am attempting to setup RH 6.0 Gnome on a 6340 HP Pavilion with a M40
14 inch monitor.
If I use the HP video drivers in RH 6.0 I can get fair results with the
vertical Lines on the right side of the screen resembling a railroad
track instead of sharp vertical lines.
The video card is a ATI 264 VT4 (English) (Direct X) Range Pro. RT 6.0
list this card and I am using that setting.
The Monitor is a Pavilion M40 FCC ID A3KM065 which was manufactured by
Philips Electronics Industries _ Taiwan.
It also has the following additional identification information HP
5258A, Serial TW 74405032, TCI D5282-6000, and 1020 Low Emission
Display.
Does any one know where I can get the setup / driver files for this
monitor or its equivalent?

Winmodem is a USR trademark. Other manufacturers can't label theirs as
winmodems. The generic term is "software modem" or "softmodem."

Howdy I know this is going to be a difficult one but here goes. Ive got a
Dell Latitude CPi(233MMX) and a Adaptech 1480 Cardbus SlimSCSI PCMCIA card
with a IOMega Jaz (2GB)Drive installed. Now the Laptop im using is the one
I use for work so I really don't want to touch the internal HD because that
would just be inviting Murphy's law to use me as a Case Study. What I
would like
to try is booting Redhat on the Laptop using the Floppy Drive with LILO on
it and having the Root File System on the Jaz drive. From reading the
Documentation it looks like it is possible if one is Careful and goes by the
book. What would help me out Greatly would be if someone could point me in
the right direction of a Image file for a floppy boot from a External SCSI
Device hanging off of a PCMCIA Adapter.
Oh I Installed a Root Filesystem onto the Jaz Drive using the Redhat 6.0
Bootdisk and PCMCIA Disk. It worked like a charm but it didn't give me the
ability to make a Bootdisk for PCMCIA.
Thanks in Advance

Actually, there are others on the USB mailing list (myself included)
quite intereste in getting USB scanners working. The devil is in the
documentation.
As someone who actually has the hardware, this fellow could be of
some use if even only for beta testing.
The best advice at this point would be to seek out or solicit
documentation for yourself or to be sent to Linus (Torvalds).

Well, there could be lots of reasons, depending on what modem tool
you're using. Either a device file needs to be writable by everyone
("chmod 777 <device-name>"), or your modem program must be run "setuid
root" (which means when you start it, it runs as the root user so it
can access devices mere mortals can't). I don't know much about these
tools myself. Check any manuals (e.g., "man xxx" where xxx is the
name of your modem program). Also, some programs take -d as a switch
which prints out debugging info, which may give a clue.

All versions of the Ensoniq AudioPCI are not soundblaster
compatible. But that's not a problem since 2.2.x has native drivers
for both major variants. If you don't know which one you have it's safe
to compile both since they use the PCI IDs to determine if it's a supported
card or not. A REALLY nice thing here, if you're used to ISA cards, is
that it is completely plug and play (not Plug'n'Pray ;)
In your case, under the sound config menu of menu/x config, use
the ES1371 driver.
(BTW, for the ES1373 chip, use the ES1371 driver. The 1373 is
simply another revision of the 1371 and uses the same PCI ID number.)
- Chad,
who wishes Creative pushed their Ensoniq tech instead of that
SB 16 PCI card... gag.

What's Linux 4.0? Do you mean the Slackware distribution, version
4.0? RedHat 4.0 (which is really old)? I think the 8505 will always
work as long as the SCSI card you use on the system is supported by
the kernel. See next answer.

Just about anything supported by the kernel. Please specify which
kernel version. I use a BusLogic -- I mean Mylex -- BT-948. Look at
the choices you're given when configuring the kernel (make config,
make menuconfig, or make xconfig).

Last time I rebooted into Windoze (95) to run a program there to
upload new firmware to my 8505 tape drive, 'doze had completely
forgotten about my SCSI card (making my tape drive and CD-ROM drive
useless), and nothing I did could make it find it again. I gave up,
went back into Linux, and haven't booted Windoze in several
months. :-)
It might work for you though, but this *is* Windoze we're talking

Either set the termination jumper on the last device in the chain, if
there is such a setting on that device. Or put a separate terminator
device on the SCSI cable right after the last SCSI device.
