iPXE & EFI BIOS

iPXE & EFI BIOS
Hello all!

I'm planning to deploy several diskless stations with network boot from the iSCSI target on dedicated storage server.
The target OS will be Windows 7 x86.

The mainboard in the diskless computers is ASUS P8B75-V, ethernet controller is Realtek 8111E.

The stations will be placed in not so easy accessible location, so I don't what any storage inside them. As a fallback solution I plan to use USB stick with iPXE image, but the best would be to burn iPXE into the MB firmware.

And here I'm stuck.
The BIOS image I've downloaded from ASUS site is quite clear an EFI image. I've opened it with MMTool Aptio (4.50.0023) and I can see and modify the content of the image.

But I have no idea how to embed the iPXI EFI image into the BIOS. Should I just add an iPXE.efirom to the image? Or should I replace something? Do I have to link iPXE.efirom to VID&PID or not?

I can't attach a report of the MMTool on the ROM image, so I'll embed it at the end of the post.

Could you please give me a hint how to do it?

Thank you!

RE: iPXE & EFI BIOS
If you haven't already read the information at http://ipxe.org/efi/vision I urge you to read that to understand how iPXE can help you in an UEFI environment. From what I understand, adding VVVVDDDD.efirom to the MB firmware should give you a network boot target in EFI, but you only have the basic features an EFI environment gives you (no iPXE HTTP boot and such). The EFI firmware should probably already have a PXE-enabled firmware for the network card that works.

Do you really need to run the machines in EFI mode for your use-case?

I've done it several times but I still don't understand a proposal given in the vision. I see the petition that UEFI is a step back in regards to iPXE, but what can I as final user do with it? There is no ROM for the MB I'm using other than EFI based.

Yes, there is an PXE module. Actually I don't know any modern MB that doesn't contain PXE inside. It's a solution (to do chainloading of the iPXE image), but it would be nice to have iPXE inside the ROM.

How can I do it if there is an EFI BIOS inside?

RE: iPXE & EFI BIOS
Most UEFI-based motherboards can be coerced into booting in BIOS mode for legacy operating systems (like Windows XP). Check your motherboard manual for how to enable this feature. It might be quite well hidden. If you try to boot ipxe.usb (iPXE on a USB stick) or ipxe.iso (iPXE on a CD) using the USB/CD boot feature of the motherboard it should automatically start it in BIOS mode (if it actually works). If iPXE loads and you can get to the shell you have just confirmed that your MB supports BIOS boot. Then the next part is just to figure out how you can force it to PXE boot in BIOS mode.

RE: iPXE & EFI BIOS
Looking at http://dlcdnet.asus.com/pub/ASUS/mb/LGA1...8B75_V.pdf, page 3-28 indicates that the firmware supports both EFI and legacy boot mode. Below you also see some mention of legacy mode Option ROM (which is what iPXE is if you burn it into the ROM).

RE: iPXE & EFI BIOS
Today I've booted it again and found, that it firstly goest into AMIBIOS legacy BIOS mode, and then, if I press F1, it goest into EFI.
The question is - how to burn the iPXE code into the "legacy" BIOS if the image I download from ASUS site looks and feels like EFI BIOS? I was unable to find explanation about it.

I still have an option to boot the computer with PXE, and chainload looks to work nice, but also there is an option to enable "EFI IPv4 stack" that I don't understand, will investigate it in more details tomorrow.

I must admit, I just don't understand what the EFI is, and how to work with it.....

RE: iPXE & EFI BIOS
Hello all!

Today I've successfully installed Windows 7 to iSCSI target, smothly and without any issues.
I still don't understand how to embed iPXE into BIOS, but BIOS->PXE->iPXE chain takes ~15 seconds, so for me it's not a problem.

RE: iPXE & EFI BIOS
Hi,

I own an UEFI Board now, it's an ASUS P8Z77-V LX and I boot iPXE from dnsmasq on OpenWRT. However it's possible to sanhook or autoboot my iSCSI drive and boot linux but there's a problem booting windows cause iPXE is not registering the iSCSI volume as BIOS drive.

I found an interesting iBFT thread here, but it couldn't help me solve my windows boot problems.

The message "Registered as BIOS drive ..." does simply not show on my UEFI board.
As NIL explains it won't be possible to install or boot windows without hooking the drive as BIOS drive.

Is it an UEFI issue? Please explain me how to fix it!

best regards

RE: iPXE & EFI BIOS
masterr-10da: You are booting your system in BIOS legacy mode, right? sanboot and iSCSI support doesn't yet work in UEFI mode, and UEFI iPXE support is not yet in what we'd call production level stability (still too many things that don't quite work right).
