View 3 Replies View RelatedFedora Installation :: Hard Drive Naming Convention?
Mar 23, 2010I just installed Fedora 12 and grub is not working for me. I have 2 physical drives, and installed Fedora on sdb (win xp is on sda). I picked the option that the computer booted from sdb when I installed. I then went and switched the boot order in the bios so that the computer would boot from sdb. Now Fedora boots fine, but when I try to boot into windows I just get a blinking cursor. I tried booting to windows manually (via picking that drive from the bios options) and that works fine.
I tried to edit grub.conf, but wasn't sure how to address the appropriate hard drive. How do I know what to fill in? The linux drive is (hd0,0), and grub tried to make windows (hd1,0). How do I know what to put in (hdx,y) for the windows partition? Grub tells me I have a /boot partition so everything is relative to that.If I'm way off base, please let me know. Is there a way I can just re-run grub so that it looks for everything anew? I also looked at device.map and sda is hd0.---------- Post added at 02:42 PM CDT ---------- Previous post was at 02:37 PM CDT ----------If it helps, this is my grub.conf:

Programming :: Passing Data From Interrupt Handler Function To Tasklet Function?
May 18, 2010I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

Programming :: Surface Fitting Using NR Function Svdfit ( ) In C Programming?
Sep 16, 2010fit a surface i.e. W(x,y) using svdfit() provided by "Numerical Recipes in C". svdfit() is written for curve fitting and not for surface fitting.But one can use svdfit(), as claimed by authors of NR book, to do surface fitting. On page 680 of NR book, authors have given a hint on how to use svdfit() for fitting a surface. But I have not understood it.This link may be helpful (Chapter 15 th is relevant here.):[URL]This is my problem:

Fedora :: Convention For Permanent Partition Mount Points?
Aug 24, 2009If /mnt & /media are for temporary mount points and removable drives, what is the usual convention for locating permanently mounted partitions for all users on the computer? e.g. I have a partition for photographs, I'll just call it "photos" would it be bad form to mount it as /photos or something like /my_hdd/photos ?In practice it probably won't matter, but I want to make sure it's easy for anyone else to perform admin tasks on the computer when I'm not available.

Nov 18, 2010This is my file, named xxx.c. And there are two functions in it.
[code]...
When I try to compile the whole project, I used -ffunction-sections,-fdata-sections to generate the .o files, use Wl,--gc-sections -Wl,--print-gc-sections to link to the exacutable file. gcc 4.3.2 ld 2.18 Debian 5 After the first time I compiled it, I got a list of Removed functions. But one second later, I rememberd that I forget to close the Compile Switch: Debug. Then I had to recompile it and got another list. Compare these two lists, I found that , bxx isn't on the second list. First I guess that bxx is a debug function but never used in debug mode, and it won't be compiled in release mode. I check the source and find that there was no compile switch for bxx. But it's caller function axx, is removed, both the debug switch is on and off. I try to compiled the project for several times , but the result is the same. I can't realized it , why? Is that the --gc-sections won't remove all the functions not used?
