A quick question, haven't done enough research yet.
Under 4.7-R and 5.1-R, I've found a file that won't copy to a floppy.
In exploring a memory test available at:
<http://memtest86.com/>
There are two distributions in question:
'Linux Memtest86 v3.0 Source and binary Package'
'Linux Memtest86 v2.9 Source and binary Package'
Each of these distributions comes with a precompiled disk image
called 'precomp.bin':
% ls -ln memtest86-*/precomp.bin
-rw------- 1 1001 1001 84480 Feb 28 2002 memtest86-2.9/precomp.bin
-rwx--x--x 1 1001 1001 84420 May 21 2002 memtest86-3.0/precomp.bin
When copying these to a floppy as root (using two different machines,
and several floppes for testing:)
# dd bs=8192 of=/dev/fd0 if=memtest86-2.9/precomp.bin
10+1 records in
10+1 records out
84480 bytes transferred in 3.775199 secs (22378 bytes/sec)
# dd bs=8192 of=/dev/fd0 if=memtest86-3.0/precomp.bin
dd: /dev/fd0: Invalid argument
10+1 records in
10+0 records out
81920 bytes transferred in 3.731600 secs (21953 bytes/sec)
Got any quick clues, or should I just file a PR now? (I don't
even know what to report, really...)
