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:

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:

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

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

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

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

Good day again Daniel, So the first thing I did was to remove the >NUL for your XMSDSK line and put a PAUSE after it in AUTOEXEC.BAT. That way, I could see the error message: *** XMS RAMdisk v1.9I (FU - 08/98): XMS get free mem error. Then I noticed that if you run AUTOEXEC.BAT manually from the DOS CLI, XMSDSK actually succeeds! So that led to a new test: Duplicate the XMSDSK line. ...

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
