>This README file describes how to patch IDE driver source file, 
>rebuild the Linux kernel, and measure IDE performance. 
>
>Step I: Patch the Linux IDE driver source file 
>1. The Linux kernel including driver source files are all placed in 
>  the directory /usr/src/linux. You have to change your directory 
>  /usr/src in your console. 
>
>      #cd /usr/src 
>
>2. Before patching your Linux IDE source file, you should decompress 
>  your patch file. 
>
>      #gunzip xxx-patch-xxx-vpide.gz 
>
>3. And then you will find a file "xxx-patch-xxx-vpide" in the current 
>  directory. This file is a patchfile that the Linux utility "patch" 
>  can read. 
>
>      #patch -p0 <  xxx-patch-xxx-vpide 
>
>  Note: Setting parameter -p0 gives the entire file name unmodified. 
>  
>Step II: Rebuild the Linux kernel 
>1. Change the current directory to /usr/src/linux 
>
>      #cd linux 
>
>2. Configure the system. The system will ask about driver settings. 
>
>      #make xconfig 
>
>  Note: If you are in text mode, try "make menuconfig". 
>
>3. The system will pop up a "Linux configuration window" window 
>  with many driver buttons. Find out the button "ATA/IDE/MFM/RLL support"

>  and press it. Press the button "IDE,ATA and ATAPI Block devices". 
>  The system will pop up another window. Select "VIA82CXXX chipset support".

>
>  Note: Pay attention to your CPU type and check if your system 
>        supports multiple processors. If your system is a uni-processor

>        system, disable the multiprocessor support. 
>
>4. Find out the dependencies of source files and the system will 
>  build a new Makefile. 
>
>      #make dep 
>          
>5. If you used to build Linux kernel, you should clean old object 
>  files and force building new kernel. 
>
>      #make clean 
>
>6. And you can build a new kernel image. 
>
>      #make bzImage 
>
>7. It is also possible to "make install", if you have lilo installed 
>  to suit your kernel makefile. 
>
>8. Then you have to check /etc/lilo.conf to see if the image point 
>  to /boot/vmlinuz. On the other hand, there must be the line 
>  "image=/boot/vmlinuz" in your lilo.conf. 
>
>9. Run "lilo" command in your current directory and you will see 
>  the prompt "Added linux *". 
>
>10. Reboot Linux system. You will see the boot message shown below 
>    if using the south bridge vt8233a. 
>    
>    "VP_IDE: vt8233a (rev 00) IDE UDMA133 Controller on pci:slot-num" 
>    
>Step III: Measure IDE performance 
>Use the "hdparm" utility to test IDE performance. The utility 
>provides a command line interface to various hard disk ioctls 
>supported by the device driver. The following options are available 
>for how to enable/disable DMA, change the UDMA mode, and measure 
>the data transfer throughput. 
>
>1. The parameter -T is essentially to measure the throughput of the 
>  processor, cache, and the memory of the system, -t is to measure 
>  how fast the drive can sustain sequential data reads. 
>
>    eg: hdparm -tT /dev/hda 
>
>2. The parameter -d1 is to enable DMA mode, -d0 is to disable DMA mode.

>
>    eg: hdparm -d1 /dev/hda  for enable DMA 
>        hdparm -d0 /dev/hda  for disable DMA 
>
>3. The parameter -X [16~18, 32~34, 64~70] is to switch the transfer mode,

>  16~18 for SDMA 0~2, 32~34 for MDMA 0~2, 64~70 for UDMA 0~6. 
>
>    eg: hdparm -X70 /dev/hda  for UDMA 6 
>
>4. The parameter -i to check the current transfer mode.
