Two additions to MEMDISK to support OS drivers. The "safe hook" structure ("Safe Master Boot Record INT 13h Hook Routines") is a means for an OS driver to follow a chain of INT 13h hooks, examining the hooks'' vendors and assuming responsibility for hook functionality along the way. For MEMDISK, we guarantee an additional field which holds the physical address for the

Good day to you, too. No worries about the delay. I understand how busy everyone is with SYSLINUX. Gladly, the project continues to develop and improve. With that said, thanks for today's flurry of activity regarding my reported problem. Impressively, the debug version of MEMDISK that you had directed me to use appears to have done the trick. Results below. command line:

hi everyone. i have a small tftp/pxe server i use to install different OS's without having to burn countless cd's (not all the machines i work on support usb boot). until recently, these were mostly linux/bsd-based systems (plus freedos). recently i've been trying to deploy a network-based windows installation, by booting windows pe (3.1, the one based on win7) with memdisk and from

Good day to all, Gert Hulselmans requested a feature for MDISKCHK.COM that would function roughly like GETARGS.COM[1] by Murali Krishnan Ganapathy: DOS SET command output for MEMDISK kernel arguments passed by previous boot-loaders. He also needed to support the case for MEMDISK-in-a-MEMDISK type situations, where all MEMDISK kernel arguments could be gathered together and output as a list

Thank you Shao I have no Linux env to compile the newest snapshot to C32 format. Instead, I downloaded the 3.83pre11 from http://www.kernel.org/pub/linux/utils/boot/syslinux/Testing/syslinux-3.83-pr e11.zip and replaced the files on my PXE server. Unluckily, it didn't work. I suspect it is not due to memdisk. I tried to use a combination of pxelinux.0(in 3.73) and memdisk(in 3.82), it did

A very special thanks to H. Peter for finding the time to [at least partially, if not wholly] scrutinize and merge the El Torito emulation code for MEMDISK! I'd like to ask that those who've previously used the stale MEMDISK-ISO switch to this latest[1] MEMDISK proper and report any failures. Gert, I believe this version addresses the PloP .ISO trouble you reported. Could you

Good day Gert Hulselmans, You had reported to me at one point that MEMDISK -> .ISO -> ISOLINUX had failed under certain circumstances. I just noticed with a MEMDISK 3.86 that specifying the "iso" option on the command-line actually resulted in the .ISO getting BIOS drive number 0xFF. I had to specify "iso harddisk=224 pause" to confirm that it resulted in 0xE0 (hd96).

For anyone wanting to boot an .ISO with MEMDISK: http://git.etherboot.org/?p=people/andytim/syslinux.git;a=shortlog;h=ref s/heads/memdisk-iso NOTE: Your protected-mode OS (Windows, Linux, *BSD) booted from such a MEMDISK will not magically find the MEMDISK image in RAM and use it as a CD without a MEMDISK driver. There are currently 0 MEMDISK drivers in the field, but that might change someday.

Hi Shao Miller, I found another ISO that doesn't work with MEMDISK-ISO. It is the ISO of the PloP bootmanager. It is a ISO which uses floppy emulation. When I boot it with MEMDISK-ISO (run from Syslinux), my PC instantly reboots. When I extract the floppy image from the ISO and boot this file with MEMDISK, it works fine. Grub4dos iso emulation works fine for this iso. When using Grub4dos

Cross-posting to the Syslinux mailing-list. Joakim Schicht wrote: > But part of the question is also about "memdisk raw" vs "memdisk iso". "raw" and "iso" are not mutually exclusive. I think that perhaps you meant "HDD versus El Torito emulation." One can do: LABEL ramwin KERNEL memdisk APPEND raw iso INITRD ramwin.iso > Lets say

Just a slight poke regarding the MEMDISK and MDISKCHK.COM possibilities available here[1]. Review by non-hpas is welcome, too. Thanks! - Shao [1] http://git.zytor.com/?p=users/sha0/syslinux.git;a=shortlog;h=refs/heads/ mdiskchk_enh2

Good day to all, For anyone who feels adventurous, there is an experimental memdisk.c32 COMBOOT32 module[1] now outside of the official Syslinux development efforts, which appears to be functional for a few test cases, but should be considered UNSTABLE. It is a work-in-progress, so please do not report bugs for it at this time. It's for use with Syslinux 3.85, specifically. It was too

Hi, I once again have a problem with memdisk failing to boot a harddisk image to update my Thinkpad X200s firmware. I extracted the harddisk image from the eltorito type 4 ISO using the isobar tool. Then I added memdisk using this image as initrd to my grub, rebooted and it boots into PC DOS and then freezes (ctrl-alt-del still works to reboot the system). Inside Qemu however it works fine

Good day Sean, Could you be interested in trying a MEMDISK from Syslinux 3.83-pre11? You could 'git clone' it or download a snapshot of the source from: http://git.kernel.org/?p=boot/syslinux/syslinux.git;a=snapshot;h=08d95ca 91f87a0c8ec452bb17e837e845738d530 There was a bit of work done with MEMDISK between 3.82 and 3.83-pre11. Let us know. - Shao Miller
