[syslinux] Re: pxelinux 2.11 unable to mount root fs

[Salman Haq]

Hi again,

I forgot to include my pxe conf file:

---
default remote-linux

label remote-linux
   kernel remote-linux
  append initrd=initrd.gz ramdisk_size=530072 root=/dev/raminitrd 
read-write
  ipappend 1
---

Thanks again,

Salman
