Hi Andrey,

I have found the problem with INT 13h 48h function. The number sectors was
wrongly updated. Now Linux Fedora 17 is booting fine.

Thanks for the help Andrey.

&gt; Hi All,<br>
&gt;<br>
&gt; I am developing an Legacy Option ROM for our controller. We are facing<br>
&gt; issue in loading FC 17 installed on our device. Windows 8 Installs and<br>
&gt; boots fine. But for FC 17 32-bit we find an error message during booting as<br>
&gt; below<br>
&gt;<br>
&gt; *&quot;error: attempt to read or write outside of disk &#39;hd0&#39;<br>
&gt; *<br>
&gt; *Entering rescue mode...<br>
&gt; *<br>
&gt; *grub_rescue&gt;*<br>
&gt;<br>
&gt;<br>
&gt; I am suspecting that INT13 routine with function 48h ( Get Extended Drive<br>
&gt; parameters). If we disable   extended functions then FC 17 boots.<br>
&gt;<br>
&gt;<br>
&gt; I would like to know in what circumstances we get the error message.<br>
<br>
a) attempt to read or write outside of disk :)<br>
b) attempt to read or write past 8MB in on BIOS in CHS mode<br>
<br>
You probably hit the latter. Apparently, grub does not like what you<br>
return from INT13 48h and falls back to CHS.<br>
<br>
&gt;                                                                                  \
If it<br> &gt; needs to be corrected then what should it be.<br>
&gt;<br>
<br>
See grub-core/disk/i386/pc/biosdisk.c, specifically function<br>
grub_biosdisk_get_diskinfo_real().<br>
<br>
&gt; Thanks in Advance.<br>
