similar to: Memdisk in Release 3.82 conflicts with a Intel BIOSupdate Image

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

I have been using memdisk (version 3.82) with no problem. I use it to boot my x86 computer with a compressed image I created/modified from an original DOS floppy bootable diskette. The original size of the image is 2.44 MB. I tried memdisk (version 3.83) and the bootable image gets uncompressed, bu the computer locks up and the las two lines in my screen are: Loading Boot Sector... Booting...

The previous MEMDISK El Torito code merge did not actually work without this.

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:

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

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

A kind request for help please. MEMDISK is causing an issue with the Dell OptiPlex GX280 and GX620 platforms. Booting a PC-DOS/Ghost, disk image is successful (and proper) when using version 3.83. See results below: MEMDISK 3.83: Ramdisk at 0x07eeaa00, length 0x007bc000 command line: initrd=images/ghostclient/280_620/osbootc.img BOOT_IMAGE=memdisk MEMDISK: Image seems to have fractional end

Hi All, I am still having troubling with PXE. Thanks for replying Shao.I did follow ur suggestions and my results have improved a bit.From Ethereal and TCPdump, I can see that the client sucessfully dowloads the file pxelinux.0 from the server but stops at this point. here is the output of tcpdump tcpdump: listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes 11:05:41.966864 IP

Let's try that patch again... Here's a better one, instead. I tested with: qemu -kernel memdisk -initrd memdsk.hdd -append pause -hda one.hdd -hdb two.hdd -hdc three.hdd -hdd four.hdd On each HDD image, I had a file (and volume label) to identify the HDD with the DOS 'dir' command. The expected behaviour was met; I wound up with DOS drive letters: C: memdsk.hdd D: one.hdd E:

hpa etal, Im trying to get PIRT running on an SBC which has no CD-ROM drive. (an 8 MB ISO which demo's RTAI - RealTime Application Interface, on linux patched with Adeos) (BTW, PIRT uses isolinux) anyway, Im trying to use pxelinux to chainload / memdisk / mboot it, Im having no success. Ive also tried booting memtest86, which I can boot on my laptop using grub, ie title memtest

<..trying again after changing outgoing e-mail options to avoid bad headers...> I'm trying to use syslinux 3.08-pre11 on a Gateway E4000 with the (sample) config file below, and the ramdisk images fail to boot if selected as a menu option, but do boot if I press ESC and type the command line manually. The two options are for the same floppy image, but the first is compressed, the

Some additional fields from the EDD-4 spec. draft for the Device Parameter Table have been added into the structure in setup.c and memdisk.inc.

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

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.

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).
