Hi, I added support in pxelinux for SDI (Wndows XP embedded images) files a few time ago for specific needs. It works well (at least for me atm) and I think I can now submit it to this list. I get a very good improvement in speed over the traditional way of loading SDI images. * Links : The 'diff -urN' patch for syslinux-2.11 (documentation included) :

Hello, the following patches should get multidisk access working. The syntax accepted is the following: (hdx,y)/path/to/file where x is the disk number and start at 0 and the y is the partition number starting at 1. So (hd0,1) is the first partition of the first disk. the other accepted syntax is using MBR's 32 bits disk signature so for example: (mbr:0x12345678,2)/foo/bar would address
