|

Hiya,
|
||||
|
||||
Last night I posted a cry for help booting Linux on a PCI based
|
||||
machine. After some investigation, the problem seems to lie with the
|
||||
Orchid Kelvin 64. To be more specific:
|
||||
|
||||
Booting linux (a variety of kernels between 1.0.8 -> 1.1.49) with a
|
||||
Kelvin card in a PCI bus on my machine produces a hang after the
|
||||
Uncompressing Linux message. If I replace the card with a random SVGA
|
||||
card in one of the ISA bus slots the machine boots correctly. I'd be
|
||||
grateful for any advice, be it a solution or merely a pointer showing
|
||||
me where to dig.
|
||||
|
||||
Thanks,
|
||||

13.1. Software Oscilloscope

|
||||
|
||||
Description
|
||||
Scope is a simple software emulation of an oscilloscope. It
|
||||
graphically displays voltage as a function of time.
|
||||
|
||||
Status
|
||||
ALPHA. First release.
|
||||
|
||||
System requirements
|
||||
Sound card with input capability supported by the kernel sound
|
||||
driver. SVGALIB is used to do the display work.
|
||||
|
||||
Detail
|
||||
Scope uses the /dev/dsp device to take audio in from the
|
||||
soundcard and displays it on the screen in a manner similar to
|
||||
an oscilloscope. Jeff claims Scope was written more for
|
||||
amusement value than for any serious purpose.
|
||||
|
||||
Where and How to obtain it.
|
||||
You can obtain source, makefile and man page for Scope from:
|
||||
sunsite.unc.edu
|
||||
(ftp://sunsite.unc.edu/pub/Linux/apps/circuits/scope-0.1.tar.gz)

Actually I think you sign the message with your private key so that it can
|
||||
then be authenticated by anyone with your public key. If you signed it with
|

your public key then anyone who possessed your public key would be able to
|

I not only have subscribed, but have also ordered all back issues. Definitely

I had this problem too. g3topbm seems to use an amazing amount of
|
||||
memory. I have 16MB plus about 12 MB swap, and that is usually
|
||||
insufficient. Sometimes it is enough if I kill x. Instead I had to increase
|
||||
my swap (by adding a swap file). 16MB memory plus 20MB swap always
|
||||
seems to be enough.
|
||||
|
||||
It seems kind of ridiculous, and of course it is a little slow since
|
||||
it is using all this swap space. It is a fun way to get your hard disk
|
||||
light to go on and stay on for several minutes!

|

|
||||
In general, you need *a lot* of memory to run the pbm tools, especially
|
||||
on images of the size of a FAX.
|
||||
Did you try to add swapspace? That may help. However, once I tried to
|
||||
rotate an image by 90 degrees, and even 80M of swapspace wasn't enough :-(
|
||||
(this wasn't a FAX, but a 300dpi scanned A4 sheet. however, the situation
|
||||
is similar for FAXes)
|
||||
|
||||
It should really be possible to handle some of the special cases of
|
||||
conversion much more efficient than pbm does it...

Probably because you told it to do so in the configuration file.
|
||||
There it says something like "boot=/dev/hda1" and you selected your
|

DOS partition there.

|

|

This is not normally happening when you put LILO in the DOS bootsector.
|
||||
Are you sure it is really caused by LILO and not some other mistake?
|
||||
|
||||

|
||||
|
||||
That is documented in many places. Many disk utilities also have this
|
||||
knowledge built-in so you can edit the bootsector using meaningful
|
||||
numbers. (E.g. Norton DE)

||||

|

LILO saves your bootsector in a file. However, from the above description
|

I doubt it was LILO that caused this problem, so maybe it did not save
|
||||
the bootsector either. If it did, look in /boot for a file "boot.0201"

Not sure how the 8900CL differs from the 8900C, but I had an 8900C and it
|
||||
was truly pathetic. Its speed was fine in DOS, but under Windows, OS/2,
|
||||
and Linux/X it was horrible. Scrolling in an xterm or shell window took
|
||||
forever, and shot the CPU meter through the roof. I now have an Orchid
|
||||
Fahrenheit 1280+ with 1 Meg and an S3 chip, and I scroll like blazes
|
||||
without affecting the CPU at all. It does have that font bug (I'm still
|
||||
running XFree 2.0), but I hardly care. I use restorefont from SVGAlib
|
||||
and I have no trouble. The card cost me about $150 mail order, and that
|
||||
was almost a year ago. I'm talking ISA here in both cases, on a 486DX33.
|
||||
I get about 58,000 xstones now, which is more than 10 times as many as
|
||||
I got with the Trident.

|
||||
|
||||
The boot record (as you have guessed) contains information about the
|
||||
geometry of the disk on which it resides: number of cylinders, heads
|
||||
per cylinder, sectors per head, and the total number of sectors on
|
||||
the disk. If your 130 drive differs in any way other than the total number
|
||||
of sectors, or the number of cylinders (and sometimes even if these
|
||||
are different) you'll get garbage.
|
||||
|
||||
This problem *must* occur, because DOS (like many other systems) keeps its
|
||||
disk references in terms of sectors and clusters, which must be translated
|
||||
to cylinder/head/sector format before the physical disk can be accessed.
|
||||
If the numbers used in this translation are wrong, all sorts of Bad Things
|
||||
can occur.
|
||||
|
||||
The format of the drive parm table in the boot sector is documented in
|
||||
the MS-DOS Programmer's Reference from MS Press and available in most
|
||||
large bookstores.

||||

Most of the fields are self-explanatory; the mysterious "hidden sectors"
|
||||
is the number of sectors one must skip over on the *phycical* disk before
|
||||
reaching the boot sector you're looking at. If your DOS partition is at
|
||||
the front of the physical disk, the number of hidden sectors will
|
||||
usually be equal to the number of sectors on one track.
|
||||
|
||||
Note the ".radix 16" line: the default radix for numbers in this fragment
|
||||
is hex rather than decimal.
|
||||
|
||||
Use a sector editor to fix up your drive parm table and you've got a better
|
||||
chance of recovering the use of the disk. Norton Utilities allows you to
|
||||
edit the symbolic contents of the DPT, and somewhere I think it has some
|
||||
other functions for the explicit purpose of rebuilding a damaged boot
|
||||
sector.

Try using a DOS boot disk and typing
|
||||
|
||||
fdisk /mbr on hte dos partition
|
||||
|
||||
Then use fdisk to remake the partition active.
