What floppies to make</H2 ><P > First we need a boot floppy. This will be a custom compiled Linux kernel image able to boot on the 7248. Then we need one or more ramdisk images. <P ></P ><UL ><LI ><P >Debian Woody</P ><P > For Debian, we need a boot floppy and one ramdisk floppy. You can download necessary files from <A HREF="http://users.linpro.no/ingvar/43p/images/Debian/" TARGET="_top" > http://users.linpro.no/ingvar/43p/images/Debian/</A > . The files are called <EM >debian-7248-boot.img</EM > and <EM >debian-7248-ramdisk.img</EM > .

I have built custom ramdisk images for the 7248. The files are called <EM >ydl-7248-boot.img</EM >, <EM >ydl-7248-ramdisk-1.img</EM >, <EM >ydl-7248-ramdisk-2.img</EM > and <EM >ydl-7248-ramdisk-3.img</EM >, and are available from <A HREF="http://users.linpro.no/ingvar/43p/images/YellowDog/" TARGET="_top" > http://users.linpro.no/ingvar/43p/images/YellowDog/</A >. You will need all the ramdisk files. </P ></LI ><LI ><P >SuSE 7.3</P ><P > For SuSE, we need a boot floppy and one ramdisk floppy.

Some versions of Netscape tend to uncompress compressed files, and we want to keep them compressed. If strange things things happen at boot time, try using another program for downloading the files, like wget or lynx. </P ></DIV ><DIV CLASS="SECT2" ><H2 CLASS="SECT2" ><A NAME="FLOPPIES-HOWTO" ></A >5.2. How to make the boot floppies</H2 ><P > Use always errorfree 1.44MB floppies for these images. The commands shown here is for a working Linux system. They might work on other UNIX systems as well. On some systems you may have to be root to write directly to the floppy drive. In those cases, so du a 'su root' before issuing the commands. </P ><P > MS-DOS users may use the rawrite utility. You can download rawrite from several places, for example a RedHat mirror as <A HREF="ftp://ftp.uninett.no/pub/linux/RedHat/redhat/7.3/es/os/i386/dosutils" TARGET="_top" > ftp://ftp.uninett.no/</A >.
