Ok thanks Ralf for your quick response. How can I go about getting red hat linux ecoff binaries for my Indy Prom version: PROM Monitor SGI Version 5.3 Rev B10 R4X00/R5000 IP24 Feb 12, 1996 (BE). I also had 'sash' (ver 6.2) on the machine--thought sash knew how to boot ELF binaries, but I got the same error (execute format error). Let me know what should be my next step to resolve this issue. -----Original Message----- From: Ralf Baechle To: Williams, Eric A Cc: 'linux-mips@linux-mips.org' Sent: 3/5/04 9:41 AM Subject: Re: DHCP/TFTP PROM error (F_magic 0x5330) On Thu, Mar 04, 2004 at 12:02:58PM -0500, Williams, Eric A wrote: > Anyone can give me insight as to what the error means. > > Illegal F_magic number 0x5330, expected MIPSELMAGIC or MIPSEBMAGIC You're feeding ELF to a machine that is expecting ECOFF binaries. That's a very old Indy firmware it seems. Ralf
