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

Hi, I was wondering what's the best standard file extension for zipped DOS disk images and ramdisks. I've been using the following standard: .zi kernels, memtest86, memdisk .igz .img.gz zipped floppy images and ramdisks I'd rather have a different extension for ramdisks, maybe .zim zipped floppy images .zrd zipped ramdisks Any ideas ? It would also be nice if syslinux

Has anybody tried to boot a dos disk via memdisk with a usb flash device as a primary hard drive? I have a 512MB flash key that when connected becomes my primary hard drive (new bios) - 0x80. If I boot a MS-DOS 7.10 floppy, one gets the command prompt and I can see the contents of my flash key as drive C:. But, if I make a image of the floppy and boot the image via memdisk, then memdisk

Hi, I'm doing a small hobby project writing some tools to put DOS boot images and Linux rescue images on a USB stick. For this I have partitioned my USB stick in 2 partitions, one 192MB partition with a VFAT filesystem (for the normal use) and a second partition with an ext3 filesystem. My aim was to provide a graphical menu (grub) to access the different images using memdisk. Since

Hi Thanx guys for the help on understanding howto read dmi info! I now have a custom boot menu for install of different linux versions based if they have been installed before (reinstall is ok for users, first install is not), and installquirks like if we detect odd hardware, we add install options to redhat installer so it can install anyhow (for instance hp dc7800 who needs pci=nommconf as

The narod.ru images are super outdated (FreeDOS kernel 2028) unfortunately.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 am trying to load an disk image as Floppy=1, og B: using ISOLINUX. My Config file reads: ------- Begining Of File ------- KERNEL MEMDISK APPEND raw floppy=1 initrd=CERC6.IMG ------- End Of File ------------ --- MEMDISK Output Snip ------ Ramdisk at 0x03b58000, length 0x00168000 command line: initrd=CERC6.IMG raw floppy=1 BOOT_IMAGE=MEMDISK Disk is hard disk, 1440 K, C/H/S =

I'm using a 5MB image which emulates floppydisk. label test kernel data/memdisk append initrd=data2/test.img c=80 h=8 s=18 floppy problems are

I tried to use memdisk 2.06 to boot a floppy image on my notebook which doesn't have a floppy drive. The boot failed, because the bootstrap code tried to reset the floppy drive (int13, ah=00). Memdisk passes reset calls on to the original int13 handler, which returns failure, because there is no floppy drive to reset (#1). Also i noted that some boot records (notably some created by

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

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

Hi, I stumbled on a rather odd problem. A brand new HP Compaq dx2200 computer didn't want to boot up pxelinux+memdisk image. The computer just gave "Disk I/O error" and stopped there. Workaround was rather simple... Just attach regular floppy drive to the motherboard and everything started working fine. I tried with older 2.05 (pxelinux+memdisk) and newer 3.31. Both produced

I just wanted to chime in and mention that I'm running into the problem with getting a "Non-system disk..." error on a system using a USB floppy when the floppy is not attached when I try to boot the system over the network using memdisk to boot a floppy image. Its actually fairly important to be able to do this, as the architecture of the hardware that I'm working with utilizes

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

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.

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

Hi all, I have pushed out a SYSLINUX 3.32-pre4. This version attempts to work around the "missing floppy drive" issue. If you have systems on which MEMDISK doesn't work without a floppy drive, I would appreciate it if you would test this out. -hpa

I have a USB flash drive that I'd like to image, and then load that image via pxelinux and memdisk. The flash drive was formatted under Windows 98 SE as FAT, and boots just fine on its own. The PXE boot process gets as far as loading the image via memdisk, but then when the boot process switches over to the RAM disk, it fails: [...PXE diagnostic information...] Loading boot
