...have a fast link so I can't download lots of stuff and I have no physical floppy disk present on any of my two machines (Celeron 400Mhz and Cyrix 233 - acts as my test client) Can I use the COM option in Syslinux to boot MSDOS directly by skipping the boot loader bit and running IBMBIO.COM in PCDOS.. or some other file in Win98SE-DOS I tried the following (what am I doing wrong??): mkdiskimage testImage 60 16 63 (-F was grumbling about not enough clusters even though i set fat_bits=16 in mtools.conf - for some reason..) losetup -o 32256 /dev/loop0 testImage mount /dev/loop0 /mnt cp -R /dosI...

...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 none of the DOS images would load using grub+memdisk (and I tried MSDOS, PCDOS and FreeDOS), I tried with lilo too and finally with syslinux (the intended usage). With both grub and lilo DOS just freezes without any output, FreeDOS and PCDOS with some output, but no output to why it crashes. Now that I added syslinux to my first VFAT partition, I get some more output, an...

...uld be a capability to chainload DOSes from drive > 0x80 without a stub. I have one question though: if (!opt.loadfile || data[0].base >= 0x7c00 + SECTOR) { /* Actually read the boot sector */ if (!cur_part) { data[ndata].data = mbr; Both freedos/msdos/pcdos option implicitly assume sethidden, but considering their data[0].base - the condition will always be false (and rightly so as the kernel overlaps with bootsector), so sethidden will not work here. Also, looking at freedos bootsectors, I think they require relocated bootsector to work (at 0x1f...

This isn't strictly speaking a SYSLINUX release, it's a change to MEMDISK and mkdiskimage to allow the creation of hard disk images with DOSEMU headers. This should make it easier to create bootable DOS hard disk images under DOSEMU. ftp://ftp.kernel.org/pub/linux/utils/boot/syslinux/Testing/ -hpa

A floppy image with Drive Fitness Test hangs in VirtualBox 3, while the same iso works fine in Qemu. Tested with MEMDISK from Syslinux 3.83-pre6. Adding raw or bigraw doesn't help. The image hangs with the text: ========================== loading bootsector..... loaded... starting PCDos... ========================== You can find the gzipped floppy image with Drive Fitness Test at the following link: http://dl.getdropbox.com/u/1649734/ubcd50/dft.img.gz Gert Hulselmans

This patch introduces extra functionality to chain.c, mainly with reference to BPB adjustments, but not only that. It expects 3 small patches I sent earlier (they are included for easy reference, patches 1-3/4). The changes introduced are: 1) file and boot sector use separate options to control load address and jump address (if applicable). Options are as described below: *

It appears that the 3.74 completely broke the "keeppxe" directive -- not due to the command-line parser, but due to mishandling of the flag later. I consider this to be severe enough to do a short-cycle 3.75. As a result, I would like help with: a) are there any other bugs that snuck through? b) once I have a 3.75-pre1, I would really appreciate help testing it. The goal is to have

This is a bit updated set of chain.c32 changes that simplifies a few things (and in partiter part), fixes few minor issues and adds a few new features. Details are in the following commits, below is the summary and pull details at the end. Shao - any chance to peek over them ? Most of those are relatively simple changes and well tested, though of course something might have slipped my attention.
