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

...e same time even SYSLINUX A: A: A:\SYSLINUX.BIN could be possible SYSLINUX [place-to-copy-ldlinux.bin-to] [place(s) where to put bootsector(file)] I'm supporting 8086+ instead of 386+, so I need another bootloader (called MetaKern) before SYSLINUX. That other bootloader requires that I append bootsectors of the OSs I want to load: 1) Syslinux and 2) FreeDOS. Currently I do: SYSLINUX A: // write both LDLINUX.BIN and Syslinux bootsector to A: COPYBS A: A:\SYSLINUX.BIN // obtain bootsectorfile from Syslinux bootsector COPY /B METAKERN.BIN + SYSLINUX.BIN + FREEDOS.BIN A:\METAKERN.SYS //bootloader SYS...

Hello Recently I've been happily experimenting with syslinux, replacing grub and my old bootmanager. All works beautifully, but I have one question - in case of .bss bootsectors - what exactly and under what circumstances is patched in ? With syslinux used as main bootmanager - bootsectors from xp64, xp32 and [pre-syslinux] msdos 7.1 (98se) work perfectly fine when chainloaded natively as .bs (and dos also as .bss). PS. By the way - there's another "trick&qu...

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...

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

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

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,

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

HPA, a longterm reminder. See below. Can you also make a LABEL ignore other labels if no KERNEL statement is found in between? That way you could define multiple aliasses for an entry. label foo label bar label memtest kernel memtestp foo ignores 'label bar' , 'label memtest' and executes 'kernel memtest' bar ignores 'label memtest' and executes 'kernel

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,

...r_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 0x1fe0:0x7c00) - so there is potentially a room for improvement here. Would patches adding such functionality be considered ?

Apparently there's a semi-new feature in SYSLINUX that will allow you to, from what I've heard, boot DOS. I've got a portable USB flash drive and I've managed to make it multi-boot with disk images, but that takes quite a bit of memory. I think bootsector booting is the best way to go, but I have no idea how to do it. Tell me if I've got this right: So, I want to get a flash

Okay, spending the time to dot t's and cross i's (or something like that), I think I have something now that can be called 3.00-worthy, so let's call it a release candidate. Changes over the earlier 3.00 prereleases: - -m and -a options now supported by the DOS installer. - PXELINUX now allows IP addresses, FQDNs, and truncated hostnames when specifying an alternate TFTP server
