Hi, Ian Bannerman: > I did not know the Perl version did not support the EFI/Mac changes. Comparing the help texts of http://git.kernel.org/cgit/boot/syslinux/syslinux.git/tree/utils/isohybrid.c and http://git.kernel.org/cgit/boot/syslinux/syslinux.git/tree/utils/isohybrid.in shows that the latter lacks:...

Memory usage with memdisk vs initrd a squashfs
Question, Some Linux distributions I support show two approaches for pxe booting them. One uses memdisk to boot an ISO file. The other uses pxelinux to boot kernel and initrd a squashfs file. I'm unfamiliar with the impact to memory either approach has. Like, does using memdisk permanently squirrel away a chunk of memory for the ISO file that the OS will be unable to use? Is using initrd to

SYSLINUX PXE LOCALBOOT Bitlockers
Any deviation from the expected boot process will prevent BitLocker from accessing the volume key in the TPM. One reason this behavior exists is to prevent malicious code from being loaded (such as via booting first to CD / USB / PXE, loading malware, and then continuing to boot to Windows). So what's happening here is the deviation from firmware -> PXE -> HDD is detected and the volume

...es from other versions. This applies to the executable from isohybrid.c and to isohybrid.pl. So my proposal would be to fix isohybrid.c and to declare isohybrid.pl frozen and deprecated. (As long as isohybrid.in exists it will be able to adapt to the MBR templates of new SYSLINUX versiosn.)

smbd 100% cpu, can't kill
I'm using Ubuntu server 8.10 amd64 with the 3.2.3 samba they provide. I'm using winbind for authentication. Samba is the ONLY service this box is providing for a small office (maybe 15-18 users max). I am using Backup Exec 12.5 ralus but always at night, no active users. My hardware is very overkill for my application (file server for small office, 8gb ram, Intel quad core cpu, raid 10

Syslinux and UEFI support
Hey, question if I could. What kind of support does syslinux have for UEFI? In particular I'm looking to use syslinux on Windows 8 systems.. I know I can leverage the shim to work through SecureBoot, but yeah, I couldn't find any documentation as to UEFI support otherwise. Thanks! -- Ian Sent with Sparrow (http://www.sparrowmailapp.com/?sig)

Issues with syslinux_run_command(str) and parameters
More context to this: syslinux_run_command calls into load_kernel(), and somewhere behind load_kernel things break. This is also broken at the boot: console prompt. Any commands executed at the boot: prompt also lose all parameters. --Ian > From: ian at internals.io > To: syslinux at zytor.com > Date: Tue, 29 Apr 2014 13:55:39 -0500 > Subject: [syslinux] Issues with

Issues with syslinux_run_command(str) and parameters
Thanks Ady, you were spot on, and I should have tested that scenario! I narrowed the issue down to a line in my config: ALLOWEDOPTIONS 0 The comment next to it in my config indicates this was added to disallow users dropping to the console with Escape or Tab, a restriction I would like to keep. BUT, when this is set whichsys fails to function in the manner I described. And similarly if I end up

Issues with syslinux_run_command(str) and parameters
I don't think that's it, but fair enough, try this sample config: ************************************************# Test File: isolinux.cfg default vesamenu.c32 ALLOWOPTIONS 0 LABEL Test kernel whichsys.c32 append -iso- memdisk initrd=fdboot.img -sys- initrd=fdboot.img MENU END************************************************ I am using binaries from 6.03-pre11 from kernel.org.

Issues with syslinux_run_command(str) and parameters
With the latest 6.03pre I'm seeing an issue where no parameters are passed to the image executed via syslinux_run_command(). An example of this is whichsys.c32, which uses this. E.g., using an example from the wiki page - whichsys.c32 -iso- chain.c32 hd0 -sys- chain.c32 hd1 swap - results in a loop back to the isolinux menu as chain.c32 receives no parameters. Similarly, using -iso- memdisk
