I understand that Infortrend does XOR in their ASIC. Don't know how it
would help, unless major parts of the data flow also are through
hardware, which is of course possible. The issue is then likely not so
much of whether the XOR is hardware, but how DMA based the architecture
is. For RAID5, a single block write needs to be put in nvram twice. The
original data is read and XORed over a copy, and the original parity
block is also read and XORed over that copy. Both buffers are then
scheduled for a write.
If you want to make use of DMA, it is very helpful to do the XOR in
hardware. But it is more of an extension of the DMA engine than of a
thing in itself, I feel.

Hei
I am looking for a Linux compatible TV-tuner card.
I have heard about some TV-tuner card supported by a certain

I have an ATI All in wonder card, but I am not sure weather this will

I am going to buy a dual CPU board with either a VIA Appolo Pro 266 (DDR RAM) or
a Serverworks HE-SL (regular SDRAM, but with a 128bit memory bus) chipset. The
question is, how well are these two supported by recent (2.4.x) kernels?

You can still define modelines in a XFree86 version 4 config file. However,
they are no longer global to the whole file - they are attached to a specific
Section "Monitor" section. You can also define mode sets for easy attachment to
the various monitors you may have configured. Take a look at the XF86Config man
page for further details.

I am thinking of buying removable hard disk trays and racks
for IDE drives.
It seems the best connection between the rack and the tray
is probably made by centronix socket.
So I am looking for sets with centronix supporting UDMA33/66/100.
(UDMA 66/100 may be dropped.)
I do not need hot-swap capability.
If you know good reliable ones, please let me know
the names of the products and where they are available.
If your have used removable hard disk trays,
I would appreciate for your opinion/recommendation/unrecommendation
of using such mechanism.
Thanks in advance.

Krstanovic,
You shouldn't have a ISA modem on COM2 unless your PC has only one COM port,
which is very unusual.
If you have two COM ports on the motherboard, you must disable the
motherboard COM2: as it will clash with the ISA card. It may or may not work
then.
What other serial devices do you have?
Most ISA modems were modems and COM ports on the same card, so you must get
Linux to see your ISA COM port before it will see the modem. However, I have
never come across a 56k ISA card. Are you sure its not a PCI card?

Roy Bamford

your ide cable. crc warnings indicate that data is being corrupted
(and retried until correct) between your disk and ide controller.
this can happen if the cable is noisy, too long, if your system is
overclocked, etc. you might be able to fix it simply by getting
a valie (18") udma66/100 cable (80 conductors), which provides
much better signal properties than the usual 40-conductor udma33-and-under
cable. under no cirumstances should you expect an invalid >18" cable
to work; similarly, overclocking means "expect flakiness".
in this case, you really should also put the disks on separate ide channels.

Subject: advice on video adaptor
Date: 17 Apr 2001 21:19:15 GMT
Within a few days I will buy a new computer and now I am confronted with
the choice of a videoadaptor. Can anybody give me some advice? I am looking
for an inexpensive card (about 75 euro) since 3D games are not my
interrest, but I don't want to exclude 3D entirely. I am thinking of one of
the following chipsets:
- TNT2
- S3 Savage 4
- ATI Rage 128
Which one is best supported, performs best. TNT2 is very common, but S3 is
always very good supported.
Can you use ever video adaptor as long as its chip is supported? Is tv-out
supported under Linux? Any other tricks / pitfalls?
Thanks,
Martijn Brouwer

this is to prevent you worrying... the number of mounting process per
file system is counted. I dunno where you could configure the number,
but at the specific number linux automatically starts the fsck program
(man fsck) which checks the consistency of the file systems and, if
errors are found, corrects them. if this wouldn't be done, you had to
check your file systems manually, and if you even wouldn't do that,
you'd get nonrecoverable errors sooner or later...

I have the All-In-Wonder TV using the gatos software. Watching television
works fine, but I have had some problems capturing video.
I also have the AITech WaveWatcher. I've just started configuring this one,

Reply-To: [EMAIL PROTECTED]
I have a laptop (Toshiba) with a docking station. I figured out how
to control my resolution on LCD screen 1024x768 and external monitor
1280x1024. But I don't know how to do it automatically. I am running
XFree 3.3.4 and I have 2 "XF86Config" files (one for each). I always
have to restart the X server when I dock or undock my laptop since
there is a change on the resolution.
Is there any setting/option which I can put in "XF86Config" so that I
don't have to restart the X server? Ideally, it can detect the
ejection from the docking station and switch to the lower resolution
on the LCD screen. Or it sends the resolution of 1280x1024 to the
external monitor and 1024x768 to the LCD with virtual desktop of
1280x1024. Thanks for any suggestion.

Yep. I've had mine for close to 8 years now, and not a single

You can also remove all the keys and clean the keyboard, which

I also like the copyright date on the bottom of 1983. PC keyboard

ext2fs maintains something called a "mount counter." It, er, keeps
track of the number of times the filesystem has been mounted. When it
reaches a certain level, the filesystem is automatically checked.
It's intented to detect and correct errors which are introduced during
the course of normal operation.
> Is there something wrong? And should I be worry?
There's nothing wrong. This is intended behavior. Unless e2fsck
spots a lot of errors every time this happens, at least.
I believe you can increase the max mount count using tune2fs.
