Spike, There are multiple binaries that come with syslinux. I would highly recommend that you start with the official syslinux pre-built's of pre-7 on kernel.org. You will find inside an syslinux.efi in a 64 bit folder and one in an 32 bit folder. These are the files that you need to point your clients to for efi booting. pxelinux.0 is for bios booting only.

All, I was excited to hear about EFI boot support in pxelinux >= 6.00. So I tried it. Not working. I've tried 6.02 (from source), 6.02 (from RPM), early 6.03 (from RPM) and even pulled/compiled latest source from git. 6.0.3-pre7. No love. My boot client can boot/image fine in legacy PXE mode. My dhcpd.conf looks like this: # In initial DHCP DISCOVER packet, PXE client sets option

Gene, I found a document from IBM that explains why it didn't like Vendor-Class-Identifier option I was using "PXEClient" was causing EFI boot rooms to dummy spit, that's very useful, that combined with RTFMing the PXE specs 3.0-3.2 might solve my problem if I keep at it. http://www-01.ibm.com/support/docview.wss?uid=swg21247032 Even the PXELinux docs suggest encapsulating

All, I realize this is not strictly a PXELINUX question. So I hope you'll indulge me; hopefully some of these PXELINUX experts have seen this before. And can tell me what I'm doing wrong. Or confirm my suspicions. I have a test lab server at work. Split config. The network team manages the DHCP servers, points to our TFTP server. Test subnet has 3 DHCP pools. BIOS PXE, UEFI PXE and

This document: http://www.iana.org/assignments/dhcpv6-parameters/dhcpv6-parameters.xml Has the same (plus expanded) list of cpu arch values for parameter 0x93. This list matches RFC 4578 except for values 7 and 9 which are EFI ByteCode and x86-64. Turns out RFC 4578 is wrong https://www.rfc-editor.org/errata_search.php?rfc=4578 And 00:07 *is* the correct value for 64-bit x86 clients and the

> Does the EFI version of PXELinux support http like gpxe, that would be awesome loading down those 400 meg wim Windows PE File and loading them using wimboot from ipxe (that works still with PXELinux) - only I only got it working so far with tftp that makes no difference ;) Good question. I've only ever used tftp to first load vmlinuz/initrd and then ks.cfg. Then use HTTP for subsequent

Ady: You seem to be taking (copy$paste) parts and pieces from different resources. Luke: Nope. The configuration works fine with PXE 2.01 clients, it's the UEFI PXE 3.2 that is having issues with the dhcp requests. The gospel is the Intel PXE 3 spec I'm RTFMing now. No copy and paste, I just started with someone elses configuration file that claims to support UEFI - or at least hopes to

Hi Guys, i have a problem with PXE/UEFI Boot. Legacy PXE Boot is working fine. I use Dnsmasq with integrated tftp.

Gene, All good questions. Thanks for taking time to respond. You've given me great leads to follow up w/ DHCP appliance consultant. >filename being file. I presume it looks like "/path/to/syslinux.efi" >or "/path/to/bootx64.efi" and not a TFTP URL? Correct. >> TFTP Server Name (66) -- a string. I have tried: >> - TFTP Server's IP

This is slightly off-topic for the Syslinux mailing list, but I think it is still pertinent and it might be helpful anyway. I am confused about some conflicting information regarding DHCP option 93, Architecture Type. The UEFI specification v.2.4 Errata B, Table 179, "PXE Tag Definitions for EFI", makes reference to a table in:

We are attempting to setup an automated system to build some Linux systems. We have utilised the PXELINUX bootloader after encountering the PXE 512Kb limit with bootp. We now have another issue which you may have already run into. In the DHCP configuration we specify pxelinux.0 as the bootfile, this works reasonable well, we call the Redhat vmlinuz and initrd.img files within the

Gene, As it happened I started working on this again just as you mailed me. It appears that PXE-E99 may also be related to MTFTP part of the PXE spec. IBM also says it has something to do with jumbo frames. I tried setting PXE.mtcp-ip to 0.0.0.0 to disable it but still no joy. The bootfile size shows up as zero because that relates to "option boot-size" in dhcp and doesn't seem to
