[syslinux] Invalid or corrupt kernel image

[Andrea Cogliati]

Guys,

I'm trying to use PXELINUX to boot a server with a PXE Intel NIC but I
always
Get "Invalid or corrupt kernel image" error.
TFTP server is TFTP32 but I've also tried tftpd-hpa.
The kernel I'm trying to boot is a standard Red-Hat 7.2 kernel; I tried
both 
Gzipped and bzipped images; tried unzipped images and OpenBSD images as
well.
Any advice on troubleshooting this?

Thank you in advance for any support. Ciao,

Andrea
