similar to: Question about .bs and .bss style bootsectors.

While playing with some less than usual configurations, I've got bitten few times by geometry settings in case of, usually, microsoft[ish] systems. First two examples, then the improvement idea. Example #1 My usb stick has zip-compatible geometry, which should work fine both in hdd and zip modes. It usually does, at least as far as syslinux and normal software is considered - excluding

HPA, I believe that support to boot windows CD bootsectors was broken in 3.05. I have tested 2.13, 3.00, 3.02, 3.05, 3.06, 3.08, 3.11, and 3.20pre6. All versions >= 3.05 are broken. All versions <= 3.02 work fine with the same config. The error message I get is: ================================================================ IOSLINUX 3.20 3.20-pre6 Copyright (C) 1994-2005 H.

Hi, I've coded loading NT cdrom bootsector into isolinux 1.68 myself (http://www.nu2.nu/bootcd/#multimemdisk) and I now see you have included it in isolinux 1.73 and higher. Great!!! I tried it using isolinux 1.74 and 1.75pre2, but I cannot get it to work. It says: -- Loading Invalid or corrupt kernel image. -- I use the file extension ".bin" as I see in the isolinux.asm source,

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

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: *

Hi! Facing a strange problem about not being able to access the floppy drive after booting from a rescue-floppy with 2.2.x kernel on an asus p4te mainboard, i searched the net and found a bug in the bootsector of the 2.2.x kernels. Before control is redirected to the kernel, the floppy drive is shut down in a way, that freezes the FD-Controller on recent mainboards (like the ASUS P4T-E). The

Correct the "seg=" value(s) corresponding to the "reactos=" option for chain.c32. The correct segment parameter should be "seg=0x0F80", instead of the incorrect / failing ones "seg=0:0x8000:0x8100".

HPA, is it possible to add a parameter/argument to syslinux.com/syslinux.exe to specify a file? currently it's something like SYSLINUX A: I'd like the following also to be possible: SYSLINUX A: A:\SYSLINUX.BIN It still copies LDLINUX.BIN to A:, but writes the generated bootsector intended for drive A: to a 512byte user-specified file Perhaps to allow both at the same time even SYSLINUX

hi, i ve grub in the mbr of my usb stick and now i am not longer able to use the syslinux bootmanager. i tried to delete grub from mbr with: dd if=/dev/null of=/dev/sda bs=512 count=1 but nothing changed grub is still in the mbr hope somebody can help me thx so long

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

Hi I am having problems loading bcdw (http://bootcd.narod.ru) from the isolinux bootloader. I use this to load the acronis programs. It worked fine up till version 3.51 but does not work anymore with 3.52. Here is the code to load the second bootmanager label l kernel /bcdw/bcdwboot.bin Any insights to what might be wrong here? With 3.52 I get Error! Cannot load

Dear syslinux maintainer, on a tablet pc with only a touchpad is during boot time no keyboard exist and therefore no user intervention possible to control the behavior of a bootmanager extlinux in my case. The machine is able to boot from a second drive a another as the default OS and so I think it must be potential at first time extlinux via menu to instruct, to boot from such a drive. If

Hello all, I've been following this project with interest, and have had great fun implementing Isolinux within the FreeDOS cdrom distribution. Since I'm not that an expert at Linux, I would like to know how I can *succesfully* generate a bootable image from a partition. Situation is like this: (640MB RAM on system) 60GB IDE harddisk, primary partition 1 win98 500MB extended partition

Hello, We are experiencing a strange behaviour on an embedded system (i386 PC board). The structure of our disk is the following one : - A 2GB fat16 partition with DOS and syslinux - A 100GB Ext4 partition with Extlinux an several linux images to boot on ram - A swap partition The system boot on syslinux to choose among Dos and Linux boot using chain. When Linux is chosen, syslinux chains to

Hello Peter, The attached patch contains three small (although 2 of them are fundamental :) fixes for pxelinux 1. Alignment error when more than one initramfs are loaded using initrd - the alignment of the last disk is discarded in calculations but is ALWAYS present when the loading procedure is called. As a result - the second image (cpio) is not recognized. 2. On some platforms

Calc the size of ldlinux.sys from ldlinux.bin, and check if it exceeds the limit. ldlinux.sys must fit between the bootsector and two copies of ADV whose size may vary. Thus, the size of ldlinux.sys (limit) can be at most: 65536 - 2 * ADV_SIZE - 512. Certain file systems (such as BTRFS and UFS2) will rely on ldlinux.sys being installed on the 0-64k range, thus it can't exceed the limit,
