Those who use it without crashing either use the slow driver, or use
|
|
swapping to a non-IN2000 disk, or swap to a file. The IN2000 slow
|
|
driver comes with patches to the kernel to force swapping to happen
|

in 512 byte chunks. (I know, it's lame, but it works). The "new"
|
|
driver allows 4096 byte transfers to happen -- most of the time.

I tuned dip-337 some time ago to return an exitcode from the dip script.
|
|
Now you can say "exit 5" in the script, and dip returns "5" to the shell.
|
|
This allows me to auto-redial if a recoverable error (such as BUSY)
|
|
occurs. I sent the respective patch to Uri Blimenthal but didn't
|
|
receive an answer. Seems he's not too interested. If anyone wants

the patch (actually, five or six lines more), drop me a note.

Such facilities do exist, and SparcBook computers act
|
|
quite much like you describe, however not all the things
|
|
are saveable, especially this is true with external
|
|
communication -- say, remote end wants to timeout in
|
|
X seconds, and the system is off for X+1 seconds ?
|
|
|
|
Another environment/way to do it is implemented on IBM
|
|
SP2 supercomputer (multi-cpu processor cluster) on which
|
|
processes can be migrated in between the individual
|
|
processors! (Which said processors are independent
|
|
AIX running systems each.)

|
|
|
|
On BSD systems there is a gcore program, which is used to
|
|
do several "weird" things, like checkpoint dumping of running
|
|
programs -- generally there is no way to CONTINUE such
|
|
program from a dump, just a way to make a core-snapshot..
|
|
|
|
However preservation of process external status, (like files
|
|
and TCP sockets, ) is going to be a lot more difficult!
|
|
|
|
I think that when a "shutdown" is hit on the SparcBook, it
|
|
writes ENTIRE core-state to the disk, and when it comes up
|
|
again, that state is retrieved from the disk as is.
|
|
(That includes the contents of the display RAM...)
|
|
|
|
Device drivers must also be up to the task, several (all?)
|
|
need special resetting on powerup, and running kernel can't
|
|
be thrown in, unless the devices are on proper state.
|
|
|
|
I don't think a kernel change can be done under such conditions.

I think you misunderstood the license terms. It says $99/$149 per cpu (i.e.

Argh! This is the third time I've seen this this week. The only real
|
|
difference between a 486SX and a 486DX is the math coprocessor -- the
|
|
DX has one and the SX doesn't. The _3_86SX has a 16 bit external bus,
|
|
but even it still has 32-bit registers.
|
|
|
|
Now, I suppose I should mention that Cyrix's 486SLC chips are designed
|
|
to fit into a 386SX socket, more or less, so they have a 16 bit
|
|
external bus, but Intel's 486SX does not.

I seem to remember reading a while back about a program that
|
|
checkpointed running processes. This strikes me as being a
|
|
very interesting start for a larger project. One thing that
|
|
I've always disliked is that when I reboot I have to set
|
|
everything up again (i.e. boot X, run my programs, position
|
|
the windows, etc.) I know that there are ways to save my
|
|
desktop, but I'm going one step beyond this. In a perfect
|
|
OS/World, one could hit a large Red checkpoint button, and have
|
|
the state of all running processes saved onto disk, including
|
|
the state of IPC/file desciptors/etc. and make there a way for
|
|
this to be restored upon reboot (even up to the pids of the
|
|
processes -- why not?!) I realize that this requires support
|
|
at multiple levels of the kernel to handle this persistance,
|
|
but as with many ideas, one could take an incremental approach.
|
|
In OS/2, for example, when I reboot I get the same applications
|
|
that I was running, but of course it doesn't do checkpointing
|
|
of DOS/Windows programs, or even OS/2 programs I believe. But
|
|
it looks nice. Imagine a future where one recompiles a kernel,
|
|
reboots into DOS just for the heck of it, and then boots up
|
|
Linux again, to have X come up, the raytrace that has been going
|
|
for the last week to continue, the TCP/IP connections to reestablish
|
|
themselves, and the two dosemu sessions to continue with the
|
|
EPIC Pinball games they were busy with. :) It seems that different

applications try to support this persistance in a user visable way
|
|
(i.e. an option to continue an interrupted raytrace, or a save desktop
|
|
option in a window manager), but doing it with kernel support (i.e.
|
|
SIGCHKPNT) is of course much more powerful.

Any comments? Anyone know of the program that did something like

this already? Remember this is just sort of a wishful post, not

Anyone know how to write a device driver logic for Adaptec 2940 scsi
|
|
for Linux operating system?
|
|
|
|
Or, Does anyone know of a PCI-Scsi controler that would be compatible with
|
|
all three (Dos, Linux and OS2) oeprating systems?
|
|
|
|
I would appreciate any info.
|
|
|
|
Thanks much
|
|
Farrah.

Ummm... it's certainly be possible. But make sense? Last I checked,
|
|
fast/wide scsi 2 cards weren't exactly cheap. Granted, it's faster
|
|
than ethernet, but how many people really, seriously, need more
|
|
than 10Mbits on their LAN? Especially at home (the main Linux
|
|
presence). The cabling for it would be a nightmare (25 pairs, not
|
|
just 2 as in 10baseT, *and* you have to worry about termination).
|
|
|
|
It's a cool idea, and perhaps useful in a Desk-Area-Network concept
|
|
(put an xterminal on your system via scsi and use that as your main
|
|
display, etc). But it's not well suited as a general LAN technology.

I tried setting my transports up exactly as you have them, and still
|
|
had the same problem.

Hello all!
|
|
|
|
My system: PCI/I-P5MP3 ASUS-board (BIOS ver 2.01) with NCR53C810-SCSI
|
|
(BIOS ver 3.04), SCSI-HD, Toshiba 4101B SCSI-CDROM
|
|
Kernel 1.1.19 with Drew's NCR-Driver Release 3
|
|
|
|
My problem: Every time I start playing an Audio-CD (with Workbone, Workman,
|
|
doesn't matter), my system crashes. Everything else (including
|
|
CD-Rom operations) works just fine. How come?
|

tia,
