similar to: isohybrid detecting usb vs. cdrom boot

Hello everyone, Since I have some some adventures in UEFI PXE booting ahead I tried to go with the latest syslinux development snapshot in this case 5.10pre1. But I already fail when booting from CD with Failed to load COM32 file .c32 I am a bit perplex since no name of COM32 files is given. I am trying to trace down the issue as good as I can. COM32 files present are:

Hello Peter, the following changes since commit 08b3602db548775ca819780de77686a186156ec7: H.

Hi, i did not succeed to get my test computer (Asus A7V8X-X of 2004) to boot from an isohybrid image. I tried http://www.tux.org/pub/people/kent-robotti/looplinux/rip/RIPLinux-7.0-non-X.iso which is obviously isohybrid enabled. The system has a "Promise Ultra 133 TX2" IDE controller which supercedes the mainboard BIOS. To make the system react on the USB stick i set boot option

Let's try to get this thing released. Dag: will you do your RPM buildathon on this drop? Changes in 3.74: * New UI directive, which allows a more natural way to specify a menu system (or not.) With the UI directive specifying the menu system, the DEFAULT directive can be used to select the default entry inside the menus. * kbdmap.c32: new module

When call isohybrid with option '-u', it overflows on a 32 bits host. It seeks to 512 bytes before the end of the image to install gpt header. If the size of image is larger than LONG_MAX, it overflows fseek() and cause error: isohybrid: image-x86-64-20140505110100.iso: seek error - 8: Invalid argument Replace fseek with fseeko to fix this issue.

Hello all, Past few days I was working on porting the isohybrid perl script to c. (-> https://fedorahosted.org/fedora-engineering-services/ticket/15) The first patch towards the same is attached with this mail. And the same could also be accessed from: http://pjp.dgplug.org/tools/syslinux-3.86-isohybrid.patch I would really appreciate it if somebody could have a look at it and let me know

Dear list, I have been trying to debug a build failure for a while in the utils directory on isohybrid which seems to be distro specific. On Fedora 17 64bit the build completes without problems, but under both Ubuntu 32/64bit 11.10 and 12.04 I get the following: tim at oxygen:/usr/src/git/syslinux/utils$ make gcc -O2 -luuid -o isohybrid isohybrid.o isohdpfx.o isohybrid.o: In function

When call isohybrid with option '-u', it overflows on a 32 bits host. It seeks to 512 bytes before the end of the image to install gpt header. If the size of image is larger than LONG_MAX, it overflows fseek() and cause error: isohybrid: wrlinux-image-x86-64-20140505110100.iso: seek error - 8: Invalid argument Check the offset and call fseek() multi-times if offset is too large.

I finally got around to testing the isohybrid, and it seemed to work in the creation, but in my lab, it sees the flash as a usb-fdd, and when I tried to boot from it, I just get a cursor in the top left. In linux it comes up as a cdrom. Is there a process for this, or is this a case of having to use another method. Some time ago, I had use syslinux to boot from a flash, but I had to set an

Hi, hpa: > The right thing to do is compile it with #define _FILE_OFFSET_BITS 64 > and change fseek to fseeko with the appropriate type being off_t. And for GPT names it should really use 16-bit UTF-16LE characters and not 8-bit characters padded up by the same number of random bytes from the program memory. See e.g.:

Hi, i have implemented in xorriso the equivalents of isohybrid.c options --mac and --uefi.

Hello Recently while playing with bigger iso images (>2G) looks like isohybrid from syslinux-4.02 fails. Sometimes tunning heads/sectors (-h/-s) works, because no padding is needed depending of size of the image. Some debug info provided, if more info is needed please just ask. # isohybrid -v pandereta-2010.09.13-i686.iso catalogue offset: 326 ve[0]: 1, cs: 1 ve[1]: 0, cs: 1 ve[2]: 25927,
