* [pxe] Avoid drawing menu items on bottom row of screenpxemenuscrollMichael Brown2023-01-231-1/+1
| | | | | | | | | | | | | | | Many consoles will scroll immediately upon drawing a character in the rightmost column of the bottom row of the display, in order to be able to advance the cursor to the next character (even if the cursor is disabled). This causes PXE menus to display incorrectly. Specifically, pressing the down arrow key while already on the last menu item may cause the whole screen to scroll and the line to be duplicated. Fix by moving the PXE menu one row up from the bottom of the screen. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [block] Allow use of a non-default EFI SAN boot filenameMichael Brown2017-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | Some older operating systems (e.g. RHEL6) use a non-default filename on the root disk and rely on setting an EFI variable to point to the bootloader. This does not work when performing a SAN boot on a machine where the EFI variable is not present. Fix by allowing a non-default filename to be specified via the "sanboot --filename" option or the "san-filename" setting. For example: sanboot --filename \efi\redhat\grub.efi \ iscsi:192.168.0.1::::iqn.2010-04.org.ipxe.demo:rhel6 or option ipxe.san-filename code 188 = string; option ipxe.san-filename "\\efi\\redhat\\grub.efi"; option root-path "iscsi:192.168.0.1::::iqn.2010-04.org.ipxe.demo:rhel6"; Originally-implemented-by: Vishvananda Ishaya Abrams <vish.ishaya@oracle.com> Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [block] Add basic multipath supportMichael Brown2017-03-261-1/+1
| | | | | | | | | | | Add basic support for multipath block devices. The "sanboot" and "sanhook" commands now accept a list of SAN URIs. We open all URIs concurrently. The first connection to become available for issuing block device commands is marked as the active path and used for all subsequent commands; all other connections are then closed. Whenever the active path fails, we reopen all URIs and repeat the process. Signed-off-by: Michael Brown <mcb30@ipxe.org>
* [legal] Relicense files under GPL2_OR_LATER_OR_UBDLMichael Brown2015-03-021-1/+5
| | | | | | | | | | These files cannot be automatically relicensed by util/relicense.pl since they either contain unusual but trivial contributions (such as the addition of __nonnull function attributes), or contain lines dating back to the initial git revision (and so require manual knowledge of the code's origin).

* [settings] Explicitly separate the concept of a completed fetched settingMichael Brown2013-12-051-7/+8
| | | | | | | | | | The fetch_setting() family of functions may currently modify the definition of the specified setting (e.g. to add missing type information). Clean up this interface by requiring callers to provide an explicit buffer to contain the completed definition of the fetched setting, if required. Signed-off-by: Michael Brown <mcb30@ipxe.org>

* [autoboot] Connect SAN disk during a filename boot, if applicableMichael Brown2011-01-271-8/+11
| | | | | | | | | | | | | | | | | | | For performing installations direct to a SAN target, it can be very useful to hook a SAN disk and then proceed to perform a filename boot. For example, the user may wish to hook the (empty) SAN installation disk and then boot into the OS installer via TFTP. This provides an alternative mechanism to using "keep-san" and relying on the BIOS to fall through to boot from the installation media, which is unreliable on many BIOSes. When a root-path is specified in addition to a boot filename, attempt to hook the root-path as a SAN disk before booting from the specified filename. Since the root-path may be used for non-SAN purposes (e.g. an NFS root mount point), ignore the root-path if it contains a URI scheme that we do not support.

* [build] Rename gPXE to iPXEMichael Brown2010-04-191-4/+4
| | | | | | | | | | | Access to the gpxe.org and etherboot.org domains and associated resources has been revoked by the registrant of the domain. Work around this problem by renaming project from gPXE to iPXE, and updating URLs to match. Also update README, LOG and COPYRIGHTS to remove obsolete information.

* [pxebs] Consistently interpret PXE type field as little-endianJoshua Oreman2009-11-201-1/+1
| | | | | | | | The PXE menu code also treated the type as big-endian, which went unnoticed until the first fix because its ntohs() was matched by a htons() in the PXE boot server discovery code. Signed-off-by: Marty Connor <mdc@etherboot.org>
* [legal] Add a selection of FILE_LICENCE declarationsMichael Brown2009-05-181-0/+2
| | | | | Add FILE_LICENCE declarations to almost all files that make up the various standard builds of gPXE.
* [pxe] Allow Escape to abort PXE menu selectionsMichael Brown2009-02-171-2/+2
| | | | | | Other vendor PXE stacks tend to allow the Escape key to be used to abort menu selection. Allow Escape (as well as Ctrl-C) to abort selection.
* [pxe] Display the "Press F8" prompt rather than displaying menu with timeoutMichael Brown2009-02-051-58/+112
| | | | | | | | | | | The PXE spec dictates the rather ugly feature that we have to present a DHCP-specified prompt string to the user, then wait to see if they press F8 before displaying the menu. This seems to me to be a significant retrograde step from the current situation of displaying the menu with the timeout counting down against the default selected boot option, but apparently the lack of the "Press F8" prompt causes some confusion.
* [pxe] Obey lists of PXE Boot Servers and associated Discovery Control bitsMichael Brown2009-02-051-11/+1
| | | | | | | | Various combinations of options 43.6, 43.7 and 43.8 dictate which servers we send Boot Server Discovery requests to, and which servers we should accept responses from. Obey these options, and remove the explicit specification of a single Boot Server from start_pxebs() and dependent functions.
* [pxe] Fall back to broadcast if no boot server multicast address existsMichael Brown2009-02-031-1/+2
| | | | | fetch_ipv4_setting() will zero its IPv4 address argument if no such setting exists, rather than leaving it untouched.
* [dhcp] Split PXE menuing code out of dhcp.cMichael Brown2009-02-011-0/+336
The DHCP client code now implements only the mechanism of the DHCP and PXE Boot Server protocols. Boot Server Discovery can be initiated manually using the "pxebs" command. The menuing code is separated out into a user-level function on a par with boot_root_path(), and is entered in preference to a normal filename boot if the DHCP vendor class is "PXEClient" and the PXE boot menu option exists.
