Fyi all -
2.4.1 kernel, Intel PIIX support and promise chipset support compiled in.
ASUS CUSL2, Piii 933, 133Mhz mboard clock.
IBM DTLA 307030 [7200rpm, ATA-100, 30Gb] - bought 4...
root@dblinuxII:/# hdparm -i /dev/hdb

on Intel 815e chipset (motherboard):
hdparm -tT /dev/hdb
buffer-cache reads [124.27, 136.17, 124.27] Mb/sec
buffered disk reads [35.56, 35.75, 35.96] Mb/sec
weird exact match between 1st and 3rd runs on cache-reads...
on Promise ATA100 PCi card:
cache reads [136.17, 124.27, 137.63] Mb/sec
disk reads [35.56, 35.36, 35.96] Mb/sec
124.27 is obviously a popular number..
interestingly hdb is slave on the same channel as an ATA-66, which doesn't
seem to make too much difference at teh moment [/dev/hda gets 125.49 and
25.7 Mb/sec] - would probably make more difference if trying to do
simulataneous (or overlapped - I dunno..) read/writes.
Once I get RAID 5 configured, they'll all be on a channel each - then we'll
see...

Hi,
I am looking for a fax program that can simply send/receive faxes.
I have looked at Hylafax, but it seems to be an overkill.
Could someone suggest other packages that is EASY to configure

I am running Slackware if that matters.
Thanks a million.

Actually, if your kernel has support for serial port IRQ sharing,
this isn't necessary. But who the hell needs two serial ports, especially
when you already have a modem! SO disable one anyway :)

Assuming you use LILO for booting, you can also type "linux 3" at the
prompt. The number refers to the runlevel at which you want to start. At
least for RedHat-derived distros (like the ones you mentioned), "3" is for
booting to the console, "5" to boot directly to XWindow.

There are a few possibilities here. First, is your USB port working?
Is it enabled in the BIOS, and does it have an IRQ assigned to it. Second,
does your kernel have USB support? If it's stock RH 7.0, it probably does,
but it's always hard to be sure. Third, is X configured to see the mouse?
mouseconfig works to configure gpm (the mouse-in-the-console daemon) and I
think it configures XFree 3.3.x as well, but I'm not so sure it configures
XFree 4.0.x. What version of X are you using?

What's the right driver for the SCSI card Tecram DC-315U?
On the tecram website it says, that Linux kernel contains the driver
for the card. However the only Tecram driver that I was able to find is
for DC-390 and it does not appear to recognize the card. I also read in
the kernel help that some of Tecram cards use different chipset and
won't work with this driver. It seems I just got the case. So what's the
name for the right driver?

you might as well buy an external modem since the knowledge of whether

Consider that you haven't the faintest idea what you are asking. What
you are trying to ask is if your modem will work or not. Being pci
or isa doesn't tell you that - it affects the probabilities in the
absence of further knowledge; since most modems that don't work are
pci, it must be assumed, without further info, that if you have a pci
modem then it probably won't work.

Except that I believe ECP doesn't have a standard, not a nonvariable one,
so that what bioses implement could be most anything. I'm not sure if EPP
has or had a stable standard either. I recall it all being discussed
previously in the Printing or PLIP howtos, but it seems to have
disappeared from tehre nowadays.

Whether it is interfering or not is immaterial, it can interfere or not
until it or he is blue in the face. There is no standard "modem" protocol
for a parallel port, so there is no protocol to talk to the modem with, and
there are no applications to even try it with - unless you write one.
Reverse engineer the compaq driver for more info :-).

You are an ass! I come to a newsgroup to try to learn something, not to be
berated and made to feel ignorant by a little man who makes himself feel big
pointing out his superior knowledge. In the above example I was conversing
with someone whom had asked me whether it was PCI or ISA as they were
acutally trying to help, they have the same modem and it did work.

Tape recorders bundled with radios acutally work. I find it very hard to
beleive they make a product that is totally unusable, just because it adds

I'm configuring my Toshiba 205CDS laptop for sound support. It apparently
has an ess688 sound card. It works just fine, but I can only play 8 bit
stereo 11 KHz sound files. Any higher bitrates and the CPU gets pegged and
the sound is broken.
My theory here is that there is a "native" bitrate that the sound chip
handles, and the files that I am playing need to be converted to the native
bitrate, and that is what the CPU is doing.
Any theories here? Here's my modules.conf file:
alias net-pf-4 ipx
pre-install pcmcia_core /etc/rc.d/init.d/pcmcia start
pre-install plip modprobe parport_pc ; echo 7 > /proc/parport/0/irq
alias parport_lowlevel parport_pc

I've heard about someone else with the same problem. His solution was to
run gparted which was able to write a DOS partition disklabel. Then he
was able to use fdisk to create partitions.
This is probably a bug in fdisk which seems to be unable to create new
partition tables on big disks.

You are at least partly wrong. You will be able to use software raid
with any SCSI card. There are also rather expensive hardware raid cards
with their own CPU and some memory for cache that use SCSI disks.

RAID5 means parity which means that it will need some CPU power. This is
where a hardware raid would be more useful. With raid 0 which only is
striping and no security software raid gives equal performance for a
much cheaper price.

For hardware raid, read your manual. Linux will probably see all disks
as only one SCSI disk. For software raid, read the Software-RAID
miniHowTo.

However, with the 3com 3c90x driver the card works fine for me with

you don't have any CMOS setting saying something like

Subject: Getting a faster IDE controller
From: [EMAIL PROTECTED] (Eric P. McCoy)
Date: 11 Feb 2001 14:24:19 -0500
I'm thinking about getting a new IDE controller, probably ATA/100, so
I don't have to use the sucky onboard controller. But I'm sort of new
to the world of IDE, so I have some questions.
But before we go any further, this is the setup:
Linux 2.4.0-smp
Intel PR440FX motherboard
2 PPro-200 (256k) CPUs
2 32MB 60ns EDO/ECC DIMMs
2 Maxtor 7200rpm 30GB ATA/66 disks
First concern is whether I'm going to notice a difference. From
hdparm:
/dev/hda:
Timing buffer-cache reads: 128 MB in 3.24 seconds = 39.51 MB/sec
Timing buffered disk reads: 64 MB in 11.80 seconds = 5.42 MB/sec
Which is not really great. The part that vaguely concerns me is the
buffer-cache figure; shouldn't that be, oh, about three times higher?
It was when I ran the disks on my other computer.
Second, as you can probably guess, I need to be able to boot off these
drives. I have no idea if my BIOS even supports booting from
off-board controllers, nor do I know how I'd find out.
If I can get past these two problems: Any recommendations for what
controllers work, and work well? I'd rather pay 50% more for a
controller than risk getting corrupted data.

Have you done anything with the PC to confirm that the CD-ROM drive
reads CD's properly at all (eg, from Windows)? If so, how about trying
to boot from the CD directly (set up the BIOS, if HP lets you, to
boot from the CD-ROM... I think the Mandrake CD is bootable if it's
a recent version).
If the CD-ROM doesn't function at all, check all the cabling make sure
it's connected properly and securely.
