It is recommended to use GRUB to boot the installation, simple and effective, compatible, and do not advocate loading Loadlin. GRUB can be obtained by the following ways: the original installed on the hard disk comes with; WINGRUB, GRUB FOR DOS, Dwarf DOS, and VFLOY and other software. The start-up mode and interface display may be different, but the use method is basically no different. There are two specific installation methods, which can be selected according to your needs. 1. By guiding VMLinuz and initrd.img, enter the installation first open the FC-5-I386-Disc1.iso image file, solve the VMLinuz and Initrd.img in the isolinux directory to put it on the hard disk (here we put On the first primary partition, i.e., HDA1, that is, the usual C disk). Then enter the GRUB> prompt, enter
Quote:
GRUB> root (HD0, 0)
Grub> kernel / vmlinuz
GRUB> Initrd /initrd.img
GRUB> Boot
It will be installed.
If you can't remember, please edit the menu.lst file, usually in / boot / grub directory, join
Quote:
Title FC5 INSTALL
root (HD0, 0)
Kernel / Vmlinuz
Initrd /initrd.img
Selecting the FC5 Install in the GRUB menu to enter the installation.
Second, to install by boot diskboot.img file
With the same size as a method, first open FC-5-I386-Disc1.iso, solve the diskboot.img file in the images directory to the C drive.
Then enter the GRUB> prompt, enter
Quote:
GRUB> root (HD0, 0)
GRUB> kernel /memdisk.gz
Grub> initrd /diskboot.img
GRUB> Boot
You can see the same interface as the disc starter, you can go directly to the car to enter the installation.
If you don't have a memdisk.gz file, please download it in the attachment. (If you are using a dwarf DOS, then this file is in the c: / boot / grub directory)
Similarly, if you are afraid, edit the menu.lst file, join
Quote:
Title FC5 INSTALL
root (HD0, 0)
Kernel /memdisk.gz
Initrd /diskboot.img
The difference between the above two methods: Method 1 is to enter the installation process, fast, compatibility; method two is more functions, you can enter Linux text to enter text mode installation, you can also enter Linux Rescue to enter rescue mode, you can Used to repair the system. But Method 2 has compatibility issues in some hardware environments. Everyone can choose as needed. Finally, what is the way, no matter what method enters installation, remember to choose a hard disk (hard disk) when selecting the installation medium.
X-screen refresh rate solution! Submit: xjstudy Time: Day, 12/12/2004 - 18:39 Desktop x Solutions under the screen refresh rate!
Although my Samsung display has no problem, I saw a lot of netizens on the Internet, because I gave up Linux because I was engaged in Xixin's refresh, my psychological feeling is very uncomfortable, and I am not all people's problems. I can answer. The idea is that these brothers in our teaching researchers, so write the final solution, this method does not rely on any gnome or kde, you can solve it below the command line, apply to any window manager, I It is ICEWM, of course, there is no problem, huh, huh, the following is the specific solution first run your gtf command under the terminal, the parameter is the resolution and refresh rate you want, such as 1024x768, refresh rate want 85, then I can use this: GTF 1024 768 85 The results are as follows: # 1024x768 @ 85.00 Hz (GTF) Hsync: 68.60 kHz; PCLK: 94.39 MHz Modeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772 807 - Hsync Vsync This can modify your / etc / x11 / xf86config-4 display section:
Section "Monitor" Identifier "Generic Monitor" # 1024x768 @ 75.00 Hz (GTF) hsync: 60.15 kHz; pclk: 81.80 MHz Modeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772 807 -HSync Vsync Option "DPMS" EndSection Start X, you can see the effect, if X is not started, check out the reason, it is possible to be your resolution or refresh rate is too high. In addition, you can also make fine tunes through XvidTune.
Modify / etc / x11 / xf86config-4 I think the most worthwhile article: /usr/x11r6/lib/x11/doc/readme.config/usr/x11r6/lib/x11/doc/quickstart.doc/USR/ X11R6 / lib / x11 / doc / videoode.doc Last article completely solved the problem of refresh rate. Now I will talk about it. If there is anything unclear, please read the original text. First introduce some terms: HSF: Monitor level Scan frequency, unit is kHzvsf: vertical refresh rate, unit is the "dot-clock" of the Hz graphics, the official name is Driving Clock Frequency (DCF), which means that the number of pixels emitted to the screen per second, the unit is MHzrr: Refresh Rate HR: Horizontal Resolution VR: Vertical Resolution Frame: Frame, Can't come back immediately when scanning the display of the monitor to the screen, there will be a period of adjustment time, this time it is still scanning, But it is not visible to us. Therefore, the frame is slightly larger than HRXVR. HFL: frame width, slightly larger than HR, experience HFL = 1.25 HRVFL: frame length, slightly larger than VR, experience VFL = 1.05VR
The following is a very important formula: rr = DCF / (HFL * VFL)
HFL = DCF / HSF
Or HSF = DCF / HFL
Our question is: How much is the DCF of the graphics card under a given resolution and refresh rate? How much horizontal scan frequency (HSF) is, it exceeds the maximum horizontal scan frequency allowed by the display? We see, The DCF of the graphics card here is not a problem, that is, the most general S3 TRIO64V DCF is also 135MHz. The bottleneck is the maximum horizontal scan frequency allowed by the display. We will see many modes when starting X, because of the calculation, The horizontal scan frequency exceeds the maximum horizontal scanning frequency allowed by the display. Things have not yet been completed: in the XF86Config file, there are many rows: Mode "800x600" 55.2 800 832 1064 1096 600 602 610 630 may be written Clear: Mode "800x600" 55.2 800 832 1064 1096 600 602 610 630
Mode is keyword, 800x600 in quotation marks is a name, can be casual. 55.2 is DCF, 800 and 600, of course, the resolution, 1096 and 630 are frame width and frame length (HFL, VFL). What is the middle of the middle? What do you mean? It turns out that they determine the start position and end position of the synchronous pulse. 800 832 1064 1096 This group can be understood: Horizontal resolution is 800, and the scanner sweeps to the 800 pixels. When the 832 pixels, the synchronous pulse is issued, the pulse is continuous, and the end of the 1064 pixels will end. The scanning gun will continue to sweep forward, return to the left side when the frame width is reached, scanned One line. 600 602 610 630 is vertical, or it can be understood. This is the meaning of this group.
It is very troublesome, my approach is to modify the current mode of use. For example, I use XF86Config automatically generated 800x600 mode, but the refresh rate is low. I found the corresponding line in the XF86config file. Directly increase the value of DCF, then calculate: horizontal scan frequency HSF = DCF / HFL. As long as the horizontal scan frequency does not exceed the maximum horizontal scan frequency allowed by the display. Then the X WINDOW is fine-tuned with XVIDTune.
After a few days of Linux, I look at my headache to see the display, but I can't change the new rate, find the solution, I think it will be looking for later. I have a bad memory, I have to put it here.
Open a terminal window in the desktop environment, run the xvidTune, drag vtotal with the mid button, then see the Vertical Sync (refresh rate) value change, adjust the value you want (not too high), then press Test test, if there is no problem, press SHOW to record the line displayed on the terminal window, similar to this statement "1024x768" 94.50 1024 1093 1168 1376 768 769 772 808 HSYNC vSync editing / etc / xf86config (Most of the current system is / etc / x11 / xf86config or / etc / x11 / xf86config-4) file, find the section "Monitor", you should see similar Modeline "1024x768" 94.50 1024 1093 1168 1376 768 769 772 808 hsync vsync This statement (if not, the thing will be added in the beginning plus modeline, add it to the front of the endsection, the red flag Linux is not), according to the number of the value, the value, after finishing Save, then restart xwindow is OK.
In addition, sometimes you find the position of the positive screen in WIN, I found that the screen is biased to the side (my machine is very powerful, probably the right is 3 cm). If the adjustment function of the display is adjusted, after adjustment, Win is biased, the solution is, first under WIN, then start Linux, run xvidtune, use the Left and Right buttons to adjust the screen position, then write down, then modify the file as described above. . It is really difficult, we know under Windows, there is a Control Panel to make the screen rate. Under Linux, everything about graphics is in / etc / x11 / xf86config. In the section of "Monitor", we can jump Brushing the screen rate Vertrefresh, but a range, not like a hop value under Windows. If you don't dare to edit the XF86config file directly, you can use the command xfree86 -configure to adjust.
After installing NVIDIA driver, discovering the shift of the screen has nothing but the refresh is still the default 60, it is very uncomfortable to use GTF 1024 768 85
# 1024x768 @ 85.00 HZ (GTF) Hsync: 68.60 kHz; PCLK: 94.39 MHzModeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772 807 - HSYNC VSYNC
Add this line to / etc / x11 / xf *** - 4 Monitor Section to comment out HorizSync and Vertrefresh
LIKE THIS:
Section "Monitor" Identifier "SUMSUNG SyncMaster 763 MB" #HorizSync 28-50 # VertRefresh 43-75 # 1024x768 @ 85.00 Hz (GTF) hsync: 68.60 kHz; pclk: 94.39 MHzModeline "1024x768_85.00" 94.39 1024 1088 1200 1376 768 769 772 807-Hsync vSyncOption "DPMS" endsection
Restart X, not flash, haha
Red Hat 9 has changed the display of the display and restarted into the graphical interface, you can enter the character interface, how can you change back? Thank you!
Run / usr / bin / redhat-config-xfree86, setup again!
