I am not impressed with the Power Mac at all. There's a researcher
|
|
in the lab who just got one ... all of his benchmarks run *faster*
|
|
on an 040 Quadra! ... and he using a native Power PC compiler.
|
|
BTW both the Quadra and the PowerMac are slower than a Pentium 60
|
|
running Linux.
|
|
|
|
People have to realize that a RISC cpu needs a good compiler ... this
|
|
guy is probably going to have to wait through a couple of compiler
|
|
releases before he gets decent performance ... he's ready to dump the
|
|
system now :-)
|
|
|
|
But back to the point ...
|
|
|
|
I buy systems, not CPUs. The list price of the CPU doesn't have squat
|
|
to do with the price of the system. If your buying a high-end monitor,
|
|
big disk, and >= 32Mb of RAM, the CPU price is lost in the noise.

Now what about maintenance? I agree that SGI makes fine systems (we
|

are looking at some of their higher-end workstations) but I can't go
|

to the corner computer store and buy parts for it :-).

We are seeing a problem with the IP routing in the 1.1.45+ kernels.
|
|
The default route is not being used. Putting a literal route in

the table works fine, but we have too many networks to document.

Anybody tried this on a big network?

There is ONE thing about shared library Sun people emphasize
|
|
as advantage in comparison to us. Suppose a smart user makes
|
|
his shared library; in sun he doesn't need to be root to use
|
|
it. For Linux, running ldconfig requires root privilegies.

Is this necessary; can we have local ldconfig? I'd like to have

this feature.

It needs more than WYSIWYG on terminals, it also needs a WYSIWYG way
|
|
of printing on your printer and on mine. Unfortunately, ghostscript
|
|
is not quite up to the job. It is incredibly inefficient and somewhat
|
|
buggy. From the letter that Peter Deutsch sent to Linux Journal, I wonder
|
|
how soon this situation will be improved, if ever. What is really needed
|
|
is a way for X client to use X-graphics calls to render images on an
|
|
X-print-server in the same way as X is now rendered on an
|
|
X-terminal-server.

The database back ends such as metalbase exist. But the front ends do

not yet exist. IMHO, this is a place where TCL/Tk would work well.

To get this kind of thing, you need much more than hacking. You need

This requires a standard graphics format in the same way as the PICT format
|

is a Mac standard. Hmmmm... maybe the PICT format could be adopted

|
as the graphics standard. Anyway, O'Reilly has a new Book/CD

Maybe it would be nicer to have minixdf as the default, instead of
|
|
BSD. Luckily one can remount root to use minixdf.
|
|
|
|
BTW, the mount code is confusing me. :(
|
|
|
|
I can not see where things like the mount flags are initialized. It
|
|
seems to me that it never is, but I must be wrong, since if that was
|
|
the case, things would break.
|
|

Anyone that can tell me how execution proceeds from sys_mount all the

way to ext2_read_super, etc works and where stuff is initialized, I'd

really like to know..

Yep, type 'cd /pub/linux/ALPHA/dosemu/private/devel' and you'll be in. I just
|
|
installed it on 1.1.45 and it works great! I have it set already (took almost
|
|
no time at all) to boot off of my real DOS drive. It runs Stacker so I can get
|
|
at all of my files. I have been running WP6.0 and it runs great. It is a bit
|
|
slower than running native but hell, it runs in 1024x768x256 and I'm not
|
|
complaining!
|
|
|
|
The only problem I have has to do with using more than 2 serial ports. I want
|
|
to run my XT laptop as a terminal off of COM4 but my mouse is on COM2. When I
|
|
try to use both at the same time nothing works from the terminal and the mouse
|
|
doesn't respond either. Would it work better if I shared COM3 with my mouse
|
|
since COM3 is a 16550? I must look at the serial code to see if there is
|
|
something I can do. It would be nice if someone could run WP6.0 on the console
|
|
while I run off the terminal *and* the person could use the mouse under DOS.

It doesn't sound like a filesystem problem to me. It could be anything
|
|
in the kernel that is writing to a structure referenced by an invalid
|
|
pointer. I don't see why the filesystem is particularly suspect. The
|
|
filesystem deals with blocks of data. If an entire block was misplaced,
|
|
then I'd suspect the filesystem.
|
|
|
|
If we could see a real example of corrupted data (viewed in text and
|
|
with od -x), it might shed some light on the situation. Perhaps only
|
|
certain bits are twiddled, in which case we can look at various
|
|
structures maintained by the kernel and see which ones would be likely
|
|
to change data in that pattern, if it were to write to an invalid
|
|
pointer.

Sorry to follow up my own post. I already have 2 parallel ports on 5 and 7 and
|
|
a sound card on IRQ7. Unfortunately, I don't think my multi-I/O card can
|
|
change the IRQ for COM4 to IRQ2. Thus, changing IRQs is not an option.

The kernel allocates memory for the video text buffers at startup
|
|
in con_init(). That means that for a 80x30 mode it allocates less
|
|
memory per VT, than it does, for example, for a 142x48 mode VT.
|
|
|
|
Until the kernel can dynamically alloc and dealloc memory, the VT mode
|
|
changing won't work.
