similar to: SYSLINUX: Cannot read ldlinux.sys

I've recently returned to working on FreeDOS again after quite some time, and read about an unmerged MEMDISK branch that allows to boot DOS-based ISOs. This seemed quite usefull to me as it allows for faster modifications to my code/scripts/disklayout. The general idea was to install Syslinux 3.83 to harddisk, then add the modified Memdisk from that boot-land forum, as well as my ISO. In

_ Vbox 4.2.18 VM booted with FreeDOS floppy, kernel 2041, no config.sys, no autoexec.bat, no TSR's, no memory managers. _ The booting floppy includes syslinux.com 6.02. _ Two HDD images attached to the VM, MBR + 1 FAT16 formatted partition each. Executing syslinux.com -i c: (or "d:") results in the following error: "Invalid Opcode at AD04 5080 0206 5080 2021 3666 FFFD 0083

I would like to boot FreeDOS ISO image from USB memory stick using syslinux. I have done following: 1) I created a partition to my 2GB memory stick: root at debian64:~# fdisk -lu /dev/sdb Disk /dev/sdb: 2013 MB, 2013265920 bytes 62 heads, 62 sectors/track, 1022 cylinders, total 3932160 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size

Dear All I have a problem with my Compaq EVO n410c laptop. I want to install Windows (Win98/WinXP) on it. But this laptop don't have any floppy/cdrom to boot from. I have try to use My USB Drive to boot, using syslinux. Here's my step 1. Format the USB Drive using "HP USB Disk Storage Format Tool" 2. Install syslinux (syslinux -f F:). F is my USB Drive 3.

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

Hallo, I try to boot the windows 98 bootdisk via memdisk. It doesn't work completely. Booting a freedos FD image works, booting the windows 98 image works too. But the windows 98 boot disk then should extract the file "ebd.cab" with the file "extract.com", and that step fails. Is that a syslinux problem or a windows problem? Viele Gruesse! Helmut

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

Testing the DOS-based Syslinux installer, syslinux.com, with the "-m" parameter, I found that it works as expected under MS-DOS and its DOS variants, but it seems to fail under FreeDOS (please correct me if I'm wrong). Using FreeDOS kernel v.2041 (386f32), Syslinux v.6.03-pre11 and either FAT16 or FAT32 partitions, executing: syslinux.com -m -i c: or: syslinux.com -f -m -i

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

Hi, is there an easy way to circumvent the SYSLINUX novice protection thing? intended users don't know about CTRL key to circumvent it. I'm trying to make a generic bootdisk for systems of 8086 - Pentium4. however the bootdisk is slow, so I'd like to use Syslinux + Memdisk to load a diskette image. then the text displayed to user will be: 1) FreeDOS bootdisk (accelerated, 386

Hi, I did found the problem, a combination of 2 factor. 1- I taught that I did install the latest syslinux, but in fact it was the 3.36 version. 2- Thank to kevin Connelly, he point me to a problem he got with mkdosfs command. The default FAT16 do not work, but the FAT12 do. By adding -F12 to the mkdosfs command fix the problem. The default F16 do seem to work for <8M floppy image. Thank you

Hi folks, I'm trying to make a CompactFlash bootable with SYSLINUX. The hard part is that I'm trying to run SYSLINUX on Windows 2000 and am attempting to write to the compactflash that's plugged in via a USB reader/writer. Its not working -- Windows complains about the 16-bit subsystem wanting direct access to the drive. So then is the problem SYSLINUX fighting with Windows or

Mr Anvin, is there a specific loading address used with the Syslinux bootsector (to load ldlinux.sys)? like msdos 0x70, freedos 0x60 we're trying to have a SYS program that can create bootsector for other OS's than FreeDOS only. not much luck though :( this way I'm trying to avoid the use of syslinux.exe/com (need the diskspace that it would save by not including this program) I
