Tips

  • Creating patch for RPM 
    diff -Naur olddir newdir > new-patch
- or -
diff -Naur oldfile newfile >new-patch
  • rpmbuild with distribution prefix (unconfirm)
    • rpmbuild -ba item.spec –define “dist .fc5″
    • This only works if “Release:" field has %{?dist} at the end
    • To automate for the whole system, can add to /etc/rpm/macros: %dist .fc5, then no need to use –define at each build
  • rpmbuild specify platform
    • rpmbuild -ba item.spec –target i686
  • sky2 driver status
    • FC5 kernel 2.6.20: v1.10
    • Fedora 7 kernel 2.6.21: v1.14
    • Vanilla kernel 2.6.22.1: v1.14
  • Realtek 8111B Gigabit (r8169) driver status
    • FC5 kernel 2.6.20: 2.2LK, supported (1. driver is modified, not same as 2.6.18, 2. tested at Gigabyte G33 motherboard GA-G33-DS3R)
    • OpenVZ kernel 2.6.18: 2.2K, not support
  • Building Kernel
    • Build time
      • OpenVZ kernel 2.6.18-8.1.4.el5.028stab035.1, 46min,
    • Support status for ICH9 in Intel P35/G33 chipset
      • In FC7’s 2.6.21, AHCI 2.1, has ICH9 support
      • In FC5’s 2.6.20, AHCI 2.0, has ICH9 support
      • OpenVZ kernel 2.6.18-8.1.4.el5.028stab035.1, AHCI 2.0, but only has ICH8’s device id. But tested can use with ICH9R. (on Gigabyte GA-G33-DS3R)
      • OpenVZ devel kernel 2.6.20-ovz007.1, AHCI 2.0, has ICH9 support
      • board_ahci_pi values that added after 2.6.18 If has the board_ahci_pi problem, only not able to see the drive.
    • In Fedora 7
      • Building a Kernel from the src RPM
      • Tips on building kernelFor Fedora 7 kernel, Add: “%define _enable_debug_packages 0″ under “%if %{with_baseonly}" section
      • Build kernel & kernel-devel only, use:rpmbuild -ba –with baseonly –without debuginfo –target=i686 kernel-2.6.spec
      • Build smp kernel & kernel-devel only, use:rpmbuild -ba –with smponly –without debuginfo –target=i686 kernel-2.6.spec
      • Build time with default (rpmbuild -ba –target=i686 kernel-2.6.spec): 5.5h, also it could fail~5-5.5h on Athlon64 X2 3800+, 2CPU, 256M RAM, avg 60% CPU in VMware 6
      • Debug RPMs used 188.1M + 29.7M, core kernel RPMs just 16.6M + 5M, on Fedora 7 2.6.21-1.3228 base kernel~1.25h built on Athlon64 X2 3800+, 2CPU, 256M RAM, avg 60% CPU in VMware 6~1h without debug info (_enable_debug_packages 0)
      • Solution to: modsign.sh: line 47: “segmentation fault"disable signmodules in SPEC file (%define with_modsign 0)

Rescue CDs

General requirements for a Linux rescue CD:
- Best with at least 2.6.18 kernel, support later SATA controllers
(e.g. JMICRON 36x only in 2.6.18)
- AHCI support
- Network support with newer network drivers
- Can load the whole CD into RAM
- Can install to USB key
- Optional upgradable kernel
  • System Rescue CD
    Latest version 0.3.0 at 2006-12-20, size: 150M
    Kernel 2.6.18.5 patched, can load the whole CD into RAM (‘docache’ boot option), can install to USB key
    To boot system into RAM, require 320M RAM! (nofb docache noxdetect)
  • R.I.P. Linux
    Latest version 1.9 at 2006-06-23, size: 35M (without X), 75M (with X)
    Kernel 2.6.17 patched, can load the whole CD into RAM, can install to USB key (will erase the whole USB key!)
    To boot system into RAM, only require 96M RAM
    Replace to a newer kernel is easy, just use the website’s kernel config and minor adjust with the new kernel (mainly on RAID456 and SATA drivers), and don’t patch the kernel with the tmpfs patch, then it will work.

GoldWave

  • HowTo remove static Noise
    Load up GoldWave, drag and drop the .WAV into the work area. From the pull down menus, select Effects, then Filter, then POP/CLICK using the Agressive preset. (usually Default is ok)
    After its done, run the Noise Reduction filter, using the Average at 75% preset. When done, save to .WAV and import it into Adobe for latter editing.
