similar to: pxelinux/memdisk booting MSDOS floppy image requires local floppy disk

Hi, I saw the Nov. 2006 message on Memdisk having a problem with ThinkPads. I also saw the comment in the memdisk code enabling and disabling A20. I've got a ThinkPad x61t that memdisk is not loading disk images on. The symptom is that it gets as far as saying "Loading boot sector... booting..." Then image partially runs - FreeDOS prints out its kernel message and it's

I'm having trouble getting memdisk 6.03pre18 to boot large floppies and wondering whether I'm doing something incorrectly. 1) Download http://www.fdos.org/bootdisks/autogen/FDOEM.144.gz 2) gunzip FDOEM.144.gz 3) newmkfloppyimg.sh 8 FDOEM144.img fdoem_8mb.img 4) newmkfloppyimg.sh 9 FDOEM144.img fdoem_9mb.img 5) Use following pxelinux.cfg: LABEL works LINUX syslinux/memdisk INITRD

The narod.ru images are super outdated (FreeDOS kernel 2028) unfortunately. If you are interested I could provide a 5MB FDD image template based on FreeDOS 2041 kernel (the latest available at that time in 2014) where you would just inject your ROM and EXE (and possibly adjust autoexec.bat to autostart/apply the FW update). It's a minimal FreeDOS FDD image that defaults to a clean boot with

Hi I'm using memdisk as part of CD Shell' isolinux. I've created custom floppy disk image 8440kB size. I've put FreeDOS kernel and bootsector into the floppy. Boot process goes fine with this command: isolinux /boot/memdisk initrd=/ximg/fdos.img c=60 h=8 s=36 floppy The problems begin when I try to run FreeDOS memory manager emm386 from the floppy image. my config.sys: ...

I have periodically been trying to get memdisk to boot images larger than your average 1.44Mb floppy and have always been unsuccessful. I cannot boot anything greater than 1.44Mb. The systems I'm attempting to do this with are not too old but they are not recent either. One is a Asus P5A and the other is a Intel SE440BX both with the most recent bios firmware patches available applied. If

This is a resubmission of my patch sent Jun 18, 2011 since it does not seem it was accepted. Please let me know if I am doing something wrong in how I am submitting this patch. Thank you. The below patch will swap order of sectors/track with bytes/sector to match diskette parameter table order (as pointed to by INT 1Eh).

For anyone else that runs into similar trouble and finds this thread, here follow summaries of what I've learned. To recap, our PXE server holds Dell BIOS updates in FreeDOS floppy images booted via MEMDISK.

I'm trying to use this universal DOS TCP/IP boot disk available here: http://members.iinet.net.au/~bdriver/bootdisk/ It requires an MS-DOS formatted disk created by Windows XP. It works great as a floppy but doesn't boot at all with memdisk. The problem can be simplified down to just the XP boot disk. If you make an MS-DOS startup disk with XP on a floppy, dd the floppy to an image

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

perhaps the boot-from-cdrom code in Smart Boot Manager? Bernd >>> No, since booting from CD-ROM requires that the El Torito part of the BIOS is activated, which it won't be if it didn't boot from CD-ROM in the first place. ---------------------------------------------------------------- Op deze e-mail zijn de volgende voorwaarden van toepassing:

Dear Syslinux folks, For a firmware update I am following the Gentoo Wiki [1] to create a floppy image of 20 MB, so that the vendor update utility fits. Unfortunately, FreeDOS does not load, and it seems to hang loading the FreeDOS kernel. The original FreeDOS image boots. Do you know if that issue is memdisk related? It?s started from GRUB with the commands below. linux16 /boot/memdisk

In other words: I'm suggesting to use WinImage as it also allows easy injection of new files *and* updating of already existing files. May I ask which vendor is distributing a DOS FW update that is 20MB? I'd like to see the files. Sometimes you just need the .bin/.rom and the actual FW update EXE and it would fit a 5MB FDD image.

I am planning to release SYSLINUX 2.08 in the next day or so; basically 2.08-pre9 without any further changes. So, I would appreciate any and all testers for this... -hpa

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

Can anyone please tell me how to create a bootable 10MB hard disk image for use with memdisk? I'd like to use FreeDOS. And I know little of DOS. Thanks.

If I understand things correctly, a bootable floppy has two key pieces of executable code: the 512-byte boot sector, and the kernel loaded by that boot sector. The kernel can be large, and thus
