系統(tǒng)環(huán)境：ubuntu 10.04 +x86

$ sudo apt-get install netpbm

$ pngtopnm loongson.png > loongson.pnm

說明：用來轉(zhuǎn)換的圖片必須為 png 格式，否則會有如下提示：

pngtopnm: input file not a PNG file

$ pnmquant 224 loongson.pnm > loongson224.pnm

pnmcolormap: making histogram…

pnmcolormap: 5854 colors found

pnmcolormap: choosing 224 colors…

pnmremap: 222 colors found in colormap

注意：此處 pnmquant 必須輸出到另一個不同名的文件，否則會出現(xiàn)如下錯誤提示

eg:$ pnmquant 224 loongson.pnm > loongson.pnm

pnmcolormap: EOF / read error reading magic number

pnmcolormap failed, rc=256

$ pnmtoplainpnm loongson224.pnm > loongson224.ppm

然后用轉(zhuǎn)換好的 loongson224.ppm 替換 kernel

/drivers/video/logo/logo_linux_clut224.ppm(最好先做好備份)

,然后刪除同一目

錄下的 logo_linux_clut224.c 文件，重新編譯內(nèi)核即可

$ cd /home/work/kenrel/linux26_3210/drivers/video/logo

$ mv logo_linux_clut224.ppm{,-bk}

$ cp /home/loongson/Dowload/loongson224.ppm ./

$ mv loongson224.ppm logo_linux_clut224.ppm

$ rm logo_linux_clut224.c

$ cd ///

$ make menuconfig //在內(nèi)核里面選上logo 支持
