RAID 5 is striped with a parity bit, not a CRC check. There is a RAID
level that uses a CRC check, but there's no real point to it these days,
since all modern hard drives do a CRC in hardware.
Another useful setup is RAID 0+1 -- that is, striped and mirrored.
Also, some RAID controllers allow you to specify a disk as a "hot spare" --
if another disk fails, it will automatically rebuild the RAID array using
the hot spare. Personally, I like to use RAID 5 with a hot spare.

Good scotch,... yes.
I used to have Star Office 5.1 installed, but didn't like it.
Sun has since taken over Star Office and it is now 5.2. I don't have it
but I hear its a big improvement. And Sun offers it either as a free
download or buy the CD. Suns' people are now in progress of
implementing a better interface for it as i've been told. But I can't
give any usability reports on it. Maybe someone else who has 5.2 can
relate?

Are you sure this is what you have? You say below that you have 3 32 GB
drives -- there's no way to use RAID to make a 4 GB array from that. I'd
bet that what you have is a single RAID 5 set, which has a 4 GB partition
and a 60 GB partition. In that case, you've already got the setup he
describes, just with the RAID drive split into partitions.

It depends a lot on what you're doing. If, for example, you were just
going to use the system as a file server, with the 60 GB array shared, then
there's no real point in having a separate RAID for the boot drive -- you
can easily reinstall from a CD if the boot drive fails.

Subject: intermittent MB (or is it HD)?
Date: 25 Mar 2001 23:03:41 GMT
I have a system (Debian 2.2) which fails about 10 minutes past bootup
about once a month or so (varies). Initially everything is OK, with
miscellaneous (ana)cron jobs working; then /dev/hdb appears to fail.
At that point not even the computer's reset switch will resuscitate
the drive; a power cycle is necessary to bring it back to life. This
system has an Asus P2B motherboard (Celeron 400); hdb is a Maxtor
DiamondMax 20GB IDE drive. When it fails, the following messages
can be seen (don't know if its always the same):
hdb: timeout waiting for DMA
hdb: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }
hdb: status timeout: status=0xd0 { Busy }
hda: DMA disabled
hdb: DMA disabled
hdb: drive not ready for command
ide0: reset timed-out, status=0xd0 { Busy }
hdb: lost interrupt
hdb: set_geometry_intr: status=0xff { Busy }
end_request: I/O error, dev=03:4b (hdb), sector 264034
hdb: status timeout: status=0xff { Busy }
...
with largely repeating content following this, with different
sector numbers.
It would seem that the HD is having some kind of mysterious failure.
Any chance this could be a motherboard or software problem?
Thanks in advance to any cogent comments!

I use 5.2 on Linux and it isn't too bad, but I have 512mb of SDRAM which
guarantees I don't have to go to swap. With 32mb you'd do a lot of
waiting around. SuSE includes it in their distro.
Open Office is separating the apps, dropping some of the modules where
others (like GNOME) are doing the same thing better, etc.

Look here: http://www.linuxdude.co.uk/docs/Alcatel-Speedtouch-USB-mini-HOWTO.html
He has a link to a French translation BTW.
Also, I am sitting here working on an appendix for the DSL-HOWTO for
this very subject, based on Chris's work above, and probably will be
available at LDP later this week.
Pre-release version is here (check Appendix):
http://feenix.dyndns.org/ldp/adsl/
This might expound on Chris's HOWTO a bit. I don't have this
modem, so can't give you specific personal results...
Some notes on this: Everyone I have talked to seems to agree that PPPoA
driver is the way to go. Maybe a little more work, but seems more stable
and faster, and less system load.
Chris's HOWTO references his ISPs VPI/VCI pair as 0.38 in the PPP
configuration section. Warning: This can be very ISP specific. My
provider (BellSouth) uses 8.35 for instance. If this is wrong you will
sync, but not get an IP and will be flailing at the wind. You need to
stick your ISPs required values in there.
This does not seem to be real stable at this point. Much of the
underlying software is still 'experimental'.

Hi,
Thanks for your input. You are correct, I shouldn't use upper case

I looked and there was a ttyS3 as ttyS3 root uucp 3, ## date /dev/ttyS3
(sorry dont remeber what ## was)
The dialer (RedHat) didnt work (couldn't find a modem)so I ran
setserial /dev/ttyS3 irq 3 uart 16550A
it now shows up as ttyS3 root uucp 4, 67 date /dev/ttyS3
when I use RedHat dialer to use ttyS3 I get the following error:
Application rp3 (process 1895) has crashed due to a fatal error segmentation
fault.
any suggestions would be appreciated.
Thanks,

Yes, though the problems aren't exactly as you state. Hot
plugging anythign is risky. PS/2 devices and their
controllers get confused.
Anyway, if you wnat to see what the pro's use:
http://www.blackbox.com/ BlackBox makes good stuff, but
you're not going to like the price. Cheaper stuff is, well
cheap. The stuff sold in "computer stores" is just junk.
