Not that I'm against Science Club growth or anything (in fact, I was
|

the founder & president of my high school's science club), but I think
|
||||
that charging money for Linux is against the GNU Public License.
|

While I can't tell you 100% for sure that it's against the letter of
|
||||
the GPL, it's certainly against the spirit in which it was written.
|
||||
Anyone who is well-versed on the GPL is welcome to correct me if I'm
|
||||
wrong; this is just my $.02.

Ok, the summary of my recent post is as follows:
|
||||
1- I must boot with the current A.1 disk and use LILO to change the
|
||||
hd parameters for the session. For my computer, the command is
|
||||
(at the Boot: prompt obtained by holding the ALT key down when
|
||||
LILO appears on the top of the screen...):
|
||||
|
||||
ramdisk hd=1005,12,55 (where 1005 = #of tracks, 12= #heads, and 55= #
|
||||
sectors/track)
|
||||
|
||||
2- I must install the system and change the HD parameters in one of the
|
||||
include files, then re-compile the kernel.
|
||||
|
||||
|
||||
Since I have the SLS utility for installing and using Linux, I have adequate
|
||||
documentation on compiling the kernel. Also, I have adeaquate documentation
|
||||
on using LILO to control the boot sequence from OS/2 Boot Manager. However,
|
||||
I am still not able to mount the root /dev/hda1. The system gets to that
|
||||
point and kicks an error back. I think the problem is that I have not porperly
|
||||
defined the hard drive in the new kernel. Can anyone tell me EXACTLY which
|
||||
files have to be changed and used to compilt the kernel? Also, what
|
||||
information about my hard drive will I need? I know the number of heads,
|
||||
tracks, and sectors per track but is there more? How do I go about finding
|
||||
anything more I need out? There is an include file (bootsect.S I think)
|
||||
that gives unclear instructions as to how to define a hard drive that asks for
|
||||
at least three more parameters than LILO. One of them is wpcom. Does that
|
||||
sound at all familiar to anyone? I will appreciate ANY help! Thanks!.

There is currently a hard-coded translation table from Latin1 to the PC
|

character set in kernel/chr_drcv/console.c. To support other than Latin1
|

character sets you need suitable hardware, fonts (and maybe translation

from video device drivers which don't exist at the moment...

|

Since as a Linux newbie I ran into this exact problem myself just
|
||||
yesterday, I think it's worth posting this reply.
|
||||
|
||||
'a' does not denote add but active, and means toggle the bit denoting
|
||||
whether the partition is *the* one to boot from (emphasis on "the").
|
||||
Evidently you did this an odd number of times and left partition 3
|
||||
bootable. Since 2 was presumably also bootable, this violates one of
|
||||
the preconditions of the following, which I found just now on page 543
|
||||
line -9 of Michael Tischer's "PC Intern".
|
||||
|
||||
"If the partition sector program [the code lying in 0x0-0x1be]
|
||||
detects that more than one partition is active or that none of
|
||||
the partitions are active, it aborts the booting process,
|
||||
displays an error message, and waits in a continuous loop. You
|
||||
can exit this loop only by resetting."
|
||||
|
||||
For additional information on the PC booting process you can also
|
||||
consult Amy Goebel's four articles TRYST[1-4].DOS, which I think I got
|
||||
from a Simtel mirror but now can't locate so I've put my copies on
|
||||
boole.stanford.edu, concatenated as /pub/tryst.dos. (Tryst however
|
||||
mentions only the case of no active partitions as problematic and so
|
||||
would not have helped in this particular case.)
|
||||
|
||||
The location of the error message "Invalid partition table" will be
|
||||
apparent when (as root) you do
|
||||
|
||||
hexdump -c -n 512 /dev/hda
|
||||
|
||||
The partition table lives in the last 66 bytes of this, which you can
|
||||
lay out more neatly using
|
||||
|
||||
dd if=/dev/hda of=/tmp/mbr count=1
|
||||
hexdump -s 0x1be /tmp/mbr
|
||||
|
||||
(Double check the dd command before hitting return, one badly chosen
|
||||
typo here can blow away your partition table and two can blow away your
|
||||
whole disk!! Unfortunately hexdump -s 0x1be /dev/hda prints nothing,
|
||||
seems it can seek on files but not block devices---how come Linux has
|
||||
no /dev/rhda?---whence the need for the dd.)
|
||||
|
||||
Each of the four 16-byte lines describes one partition:
|
||||
|
||||
Status(1) Begin(3) Type(1) End(3) Boot-sector(4) Size(4)
|
||||
|
||||
(n) is bytes for this field. Status is 0x80 if `a'ctive (= bootable),
|
||||
else 0x00. Begin and end are block addresses of the partition
|
||||
endpoints in units of head(8 bits)/sector(6 bits)/cylinder(10 bits).
|
||||
(What happens with disks with more than 1023 cylinders? There are
|
||||
plenty of these in SCSI-land.) Type is what operating system the
|
||||
partition contains (various flavors of DOS, XENIX, Linux, etc.) or what
|
||||
function it performs (swap etc.). Boot-sector is the absolute sector
|
||||
address of the boot sector for this partition (Tischer says it is the
|
||||
sector address relative to the partition, but this does not agree with
|
||||
what hexdump shows). Size is the total number of sectors in the
|
||||
partition.
|
||||
|
||||
Following the four partition descriptors is the short 0xaa55 (don't
|
||||
forget the 8086 architecture is little-endian, so this is 0x55 at
|
||||
address 0x1fe followed by 0xaa at 0x1ff). This serves as the standard
|
||||
signature, in the PC world, of useful data in the vicinity.

|

|

I replied directly to the poster, but I may as well reiterate here. :-)
|
||||
|
||||
It is legal under the GPL to charge a "reasonable copying fee" for
|
||||
GPL'd software. That means that the club would be free to charge for
|
||||
copying - once. After the first time, they're out of luck. As for
|
||||
renting the software, that goes *completely* against the letter and
|
||||
spirit of the GPL, which basically says that you can't make a profit
|
||||
from it.
|
||||
|
||||
I did, however, suggest selling support for Linux. :-)

I'm not sure this is legal under the GPL. My understanding of the GPL
|
||||
(which could easily be incorrect) is that you may charge a reasonable
|
||||
media fee to distribute GPL'd software, but not charge a fee for the
|
||||
software itself. Under your scheme, the customer does not keep the media,
|
||||
so the fee is for the software itself.
|
||||
|
||||
I have taken the liberty of cross-posting this to gnu.misc.discuss so
|
||||
the GPL experts can have a look at this. Is this a violation of the GPL?
|
||||
|
||||
(I'm willing to risk shooting off my mouth about things I don't
|
||||
understand fully in order to possibly help a science club avoid
|
||||
accidentally violating a software license. Flames will be duly
|
||||
considered.)

And I blew it big time. Sorry. When this idea came to me, I admit I was so
|
||||
thrilled with the prospect that I completely forgot the GPL, and somehow
|
||||
turned "reasonable copying fees" into "if you can get it you can rent it".
|
||||
Obviously NOT the intent of the GPL, and I apologize.
|
||||
|
||||
We _may_ copy Linux disks for a bargain rate, and by all means let me know if
|
||||
you'd be interested in this...but we have NO plans to folow through with the
|
||||
plans in my earlier post.
