similar to: Memdisk image size limitation?

Greetings, I had a quick question about lower memory usage by memdisk. I've read through the mail archives and found a couple of posted questions but unfortunately no answers. I know the documentation states: "MEMDISK simulates a disk by claiming a chunk of high memory for the disk and a (very small - 2K typical) chunk of low (DOS) memory for the driver itself, then hooking the INT 13h

Hi, I looked at the web http://clic.mandrakesoft.com/documentation/pxe/ch06.html, and create a floppy boot image by : dd if=/dev/fd0 of=boot.img. I copied the boot.img to /tftpboot, and my /tftpboot/pxelinux.cfg/default is : default freedos display boot.msg label freedos KERNEL memdisk APPEND initrd=/boot.img When I boot up my client, it shows : could not find kernel image: memdisk What

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...

Ofcourse when I say "mount" I dont expect >memdisk to mount it, just that set things up so that DOS mounts it there.

hpa, Seeing your post about 3.71, I wanted to get a message out even though I don't have the stats right now. I am having a problem with memdisk with a lot of shuttle computers, but also affects a variety of other hardware (low though, 5%? less?). The image that I can most reliably test against is the Hitachi Drive fitness Test.

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

hello and thanks for reading this, with the help of this group so far, i am using bootscriptor from bootscriptor.org combined with memdisk to boot a win98 boot disk. it boot into the windows98 version of dos. the cool thing about the floppy is that it has a compressed image that mounts as a drive letter. much like linux. i can create floppy images no problem. what i am trying to do is create a

memdisk fails to boot HD image, if the system does not have an HD. Has any seen this? Is there a solution? memdisk output: Disk is hard disk, 9216 K, C/H/S = 9/64/32 Total size needed = 2063 bytes, allocating 3K Old dos memory at 0x9dc00 (map says 0x9dc00), loading at 0x9d000 INT 13 08: Failure, assuming this is the only driveold: int13 = f000799a int15 = f000f859 new: int13 = 9d000008 int15

Hello, I'm investigating ways to boot a DOS floppy image stored on the FAT32 EFI System Partition using Syslinux and Memdisk. The system will be running Win8 using UEFI mode (GPT disks) and secure boot off. Change the Windows efi boot loader is the easy part... With the current syslinux's alpha version (6.0), is it possible to boot the syslinux's efi module from the FAT32 EFI

Hallo I would like to have an image of about 8Mb to boot with ISOLINUX and MEMDISK. I am not able to create an image complete of the MBR, as MEMDISK requires. I think I should emulate an 8Mb disk in memory or on a file, but I am able to do so only for a 'single partition'. Could you please suggest me a way to obtain the image? I can use Linux or Windows tools, it does not matter.

Hi list! I'm trying to make a hd image with can boot from memdisk over PXE. So this is what i did: - Created a new VM [VMware] -Installed DOS on a 100MB HD from a floppy -bootet Linux over PXE [DamnSmallLinux] -in terminal: dd if=/dev/hda of=dos.img This image [dos.img] isn't working! Memdisk loads the Image and boots the HD! The error message is something like this: I/O Device

Is there a method to reboot a memdisk (floppy) image? I'm working on a DOS-based installation floppy that needs to repartition the hard disk prior to proceeding. DOS will only recognize the updated partition table after a reboot, but I'd like to be able to save information to the currently loaded memdisk floppy disk and simply reboot the image. Possible? I haven't had any luck with

Hello list, I sucessfully booted some floppy-images within memdisk-2.0.4, but how can I boot a cd-iso-image (for example a bootable eltorito cd). Or does sb. have a wrapper or a skript which can boot an iso-image ?

I just discovered the wonderful world of ISOLINUX/MEMDISK while investigating how to make a boot CD that doesnt have floppy disk size limitations on its boot images. One thing has struck me as very odd about MEMDISK though - its support for hard disk images is restricted to physical disk images (ie. containing MBR/partition table). It doesnt support individual partition images, despite the fact

I read the following about memdisk : .... For any other size, the image is assumed to be a hard disk image, and should typically have an MBR and a partition table. The disk C/H/S geometry is determined by examining the partition table, so the entire image should be partitioned for proper operation. .... I'd like to create a bootable cd, wich boots a linux and some other tools. While

Hello syslinuxers I'm stuck with a scientific problem which gives me headaches: I have a laptop (Gateway MX3410) which has a SD memory card reader. Recently an interesting thought crossed my mind: why don't I setup a 2GB SD card as a harddrive and put some rescue tools on it. So I dug on the net and I came across the idea of using memdisk to boot floppy images without the need of a

Im trying to boot memtest86 via pxelinux, memdisk, I found this advice on http://forum.x86-secret.com/viewtopic.php?t=2906 folks are making the image match a floppy size by one of the following: dd if=memtest86+-1.xx.bin of=memtest.img bs=360k count=1 conv=sync or dd bs=360k count=1 conv=sync if=memtest86+-1.xx.bin|gzip > memtest.gz I did the former, it did suppress the warning/errors I saw

Hi, I'm trying to create a hd image to use with memdisk: dd if=/dev/zero of=doshd.img bs=1024 count=16384 and, via qemu, I installed freedos: qemu -cdrom fdfullcd.iso -hda doshd.img -boot d Everything gone ok and qemu boots freedos normally. But, when I try to use the same image on memdisk the following message appears: Invalid Operation System! I used the same process on USB key, with

I have a 32MB HD image that I can pxelinux.0/memdisk boot without issue. I would like to both memdisk and my image on a CD and then boot from the CD with pxelinux.0. Is this possible? If so how? Thanks.
