Exactly.

A multi-tiered (secondary) storage sol'n:
|
|
disk
|
|
compressed disk
|
|
cd (if avail)
|
|
tape (if avail)
|
|
|
|
complications arise w/ cd/tape, because they are removable--you end up
|
|
interrupting to tell the operator "Insert [media] volume X..."
|
|
But hey--its cheaper than robot mounted tapes, etc. ;-)

If you have an IBM mainframe to spare, and run MVS on it, you can set
|
|
it up to move files to slower discs or to tape if they haven't been
|
|
used for a while. But they remain in the catalogue and are moved back
|
|
invisibly when you next use them.
|
|
|
|
This, IMO, is the sort of thing that is required here. When you use a
|
|
file on the CD, it gets copied to your hard drive. If you don't use a
|
|
file for a week (for example) and it is identical to one on the CD, it
|
|
gets deleted.
|
|
|
|
This is also a good way of implementing compressed file systems -
|
|
instead of having the overhead of compression whenever you use a file,
|
|
you just compress files that have been unused for a week. When they
|
|
are next used you uncompress them and leave them uncompressed; if they
|
|
are unused for a week again, they will get recompressed.

|
|
Yes, but what we need to know is not when the floppy has been
|
|
changed, but rather when it is inserted. The DISK CHANGE LINE is set
|
|
when the floppy is _removed_ not when it is inserted. It is cleared
|
|
when a disk is in the drive _and_ a seek is done. Thus, in order to
|
|
detect a disk _insertion_ the drive has to be seeked endlessly. If the
|
|
period of the poll is too small, the noise gets annoying, if it is too
|
|
long the feature gets useless.

|
|
Hmm, maybe FastBack is already issuing the read/write command before
|
|
the disk is inserted? In that case, the floppy disk controller waits
|
|
on its own until a disk is inserted before executing the command. This
|
|
feature could not be used "as is" in Linux, because only one drive at
|
|
a time may be monitored that way, and many machines have several
|
|
drives attached to them. Moreover, the drive motor would have to be
|
|
spinning while waiting. For a backup program, these limitations are
|
|
ok, because it knows where to expect the disk, and because usually the
|
|
waiting period is not that long.

Try flashing to the A04 BIOS. There is an issue with the GAT (guaranteed access
|
|
time) on the PCI bus that is the likely culprit - the A04 BIOS fixes this. The BIOS is
|
|
available by anonymous FTP to dell1.us.dell.com as \bbsfiles\bios\p90a04.exe.

I think that in SCSI-Howto there was something said about this. If i remember

Hi folks,

I am looking for SCSI support for Linux for the AMD SCSI chipset.

I have a board here (from Dawicontrol), but I have no informations about the

board and the Dawicontrol hotline was wrong (German telco told me there was no

Linux should start supporting SMP now.
|
|
The commerical OS's have already, and they aren't anywhere near as
|
|
good as UNIX or Linux.
|
|
We are supposed to be ahead of, not behind commercial operating systems.
|
|
Linux is a hacker's OS, and it should be developed as hacker's would,
|
|
trying innovative approaches, not always trying to go with what is stable
|
|
and standardized. If people want that, and Linux they can use the
|
|
non-development kernels, but as for the rest of us, now is a good time
|
|
to start broadening Linux's base. It already has made a powerful impact
|
|
deep into the x86 world, so work in broadening its usefulneess is a good
|
|
idea.

Many programs/sources are found in GNU directories.

Just like you have to include a special library when you use math

|

And -lvga (or the other alternatives) is for linking in the svga
|

library, for when you use stuff from <vga.h> . You need -lvgagl if
|

you use <vgagl.h>, too.

This line is used all the time. DOS will discard the in-memory copies of
|
|
disk buffers when it sees a change on this line.
|
|
Sometimes you will see machines in which the sequence:
|
|
|
|
(insert disk)
|
|
C> DIR A:
|
|
(swap disk)
|
|
C> DIR A:
|
|
|
|
produces two times the same directory output (of the first disk). This
|
|
is because the changeline logic is defective or mis-configured (jumper
|
|
on the diskdrive)

I'll reply to this, since the original posting was mine, I guess...

This is, of course, the opposite of the situation we were originally
|
|
talking about, the same address on two different interfaces. This one
|
|
here is useful for running one machine with multiple names as well.

|
|
|
I've been asked to condense my postings about using Linux as a router for
|
|
the Networking HOWTO by it's editor; I'll be scribbling today.
