i wanted to know more about
1 different linux distributions like red hat, suse, etc etc have their
versions of linux OS. what is the difference between them
2 how to find, or what are the differences between variuos linux kernels eg
kernel 2.0.34
if linux is an open source software , then its kernel is code is free...
right ??
eg rehat calls its Linux release 5.1 as Manhattan. what are the differences
between each release.
Please point me to relevant docs.

| And finally, change your code so that instead of mapping every number
| to a bit (4B numbers = 0.5B bits) try mapping EVERY OTHER NUMBER to a
| bit (2B numbers = 0.25B). Every 3rd bit is still the multiples of 3
| (but now represents 3,9,15,21, instead of 3,6,9,12,...) and every
| Nth bit (where N is not 2) is still multiples of N. Your bit striking

That should be 4B numbers = 4B bits = 0.5B bytes,
and 2B numbers = 2B bits = 0.25B bytes.

If your floats are encoded in any way that is actually used, 3 will be

While it is true that the floating point constant 3.
will probably be represented exactly,
How ? Is it an exact binary number ?
there is no guarantee that a floating point expression
that has a nominal value of 3 will evaluate to
exactly 3.
absolutely.

I have seen some part of the source code of Linux,that is bootsect.S .
The code shows "lilo" when booting .
When bios start the computer ,then read the code of mbr ,then execute it .
Now I want to know the code in mbr (besides the partion infomation) is in
the file bootsect.S ???
Setup.S is including what ??
When booting ,the code after 0x1 (real mode ) is head.S???
the code after 0x90200( which is 2k size ) is setup.S ??

YES! 3d = 1.1b * 2^1b .
In general, all non-mantissa over[under?]flowing integers
can be exactly representing by floats.
All fractions that are multiples of exact negative powers of
two _can_ also be exactly represented. 0.25d = 1.0b * 2^-10b.
Unfortunately, multiples of other numbers to negative powers
[like the commonly use base 10] are repeaters.
Worse, even when you try to de

As indicated yesterday, it is indeed a software problem that prevents
my CD-ROM drive to find media. It works under 2.2.3, but not under
2.2.4 and 2.2.5. Strangely enough, under 2.2.4, workman started
alright, although data-cds were not recognized. But under 2.2.5,
workman also crashes with the message "no medium found". Below is
the relevant syslogin file, maybe someone can guess which changes in the
latest kernels may be responsible? My CD-writer is not affected at all.
It works under all three kernels, 2.2.3, 2.2.4 and 2.2.5. Strange!
Cheers,
