Booting BIOS Flash images via iPXE

[cpdohert]

Necro-ing the thread because I'm trying to make the same thing work.

I have a bunch of floppy disk images for flashing the BIOS on HP enterprise laptops. I'm trying to boot these over iPXE.

We have a Microsoft DHCP server configured per http://ipxe.org/howto/msdhcp. That's working fine.

Following the instructions above, I'm executing the following commands:

Code:

iPXE> dhcp
DHCP (...) .....ok
iPXE> sanboot --nodescribe --drive 0x00 http://ipxe.internal.url/8440w/FreeDOS-8440w-BIOS-Flash.img

and I get this:

Code:

Registered SAN device 0x00
Booting from SAN device 0x00
FreeDOS

and then it just hangs there permanently.

These floppy disk images work fine on a syslinux 4.02 pxe boot server.

The back end is a CentOS 6.4 x64 server running Apache 2.2.15. SELinux has been disabled and KeepAlive has been turned on. Byte range requests should be on by default in this version of Apache.
