similar to: [PATCH 1/2] chain.c32: fix bounce buffer handling

Here is a partial patch that I'm using to illustrate a few questions that I have. Looking at the gpllib write_sectors (com32/gpllib/disk/write.c) it looks like the allocated size is wrong; size is in sectors so we should adjust the alloc/memcpy by size*SECTOR. Also, comparing core/diskio.c it looks like the registers aren't even setup right. In the patch below I put an #if 0 around the

Hi Peter, Please pull the following changes. Paulo, I had to revert your "pxe: resolve names via DNS from protected-mode code" change because dns_resolv() is only implemented for PXELINUX and causes undefined symbol references for ISOLINUX, etc. Feel free to make the change again on top of the revert. The following changes since commit e7bd19def830e8341b1a100956345f1028740b9e:

Hi all, I use XP on my laptop PC, with 30 GB HD (single partition), and a 3.5" hard drive (not a stick), accessed through a USB encasing, partitioned as five logical drives. I have successfully set up syslinux to boot several Ubuntu versions from the primary USB hard drive partition, and no problems there. The problem is, I would like to have an entry in the menu, like "Boot from

Hi, Hopefully you someone can tell me what I'm doing wrong. First, the code. I placed this at the bottom of the main loop in com32/modules/disk.c as a simple test of writing to the disk: printf(" Host bus: %s, Interface type: %s\n\n", d->edd_params.host_bus_type, d->edd_params.interface_type); zero_buf = calloc(1, d->edd_params.bytes_per_sector); for(int

Hi everyone. I've read through the archives and found a few posts about using the PXE stack, but none of these really helped me. What i want to do is: Prompt the user for 2 values, desired hostname and a "pin" (just a number) and send this information over UDP to my server The problem is not the user input but the UDP part. I've tried to change the code from the post of jesse

Hi, I've checked the archives for my issue, and while there is relevant discussion, the problem the original poster was asking about didn't seem to have been resolved then either (~2 years ago). At any rate, basically what I'm trying to do is send (possibly receive) UDP packets via the PXE stack using the com32 API (using version 3.11 of syslinux). I have followed both the comboot

Why insisting? Anyway appended is a dumper version. I could put up a binery version if needed. Let me know if so. -- MartinS /*

Hey, Looks like read disk function which was launched in 3.35 isnt working. Did anyone test this on any hardware? I'm using it thru the com32 interface to read contents of the active partition of a USB boot key (syslinux). I did a sample test like: void scanAndPrint() { com32sys_t regs_in; char *sectorBuf = __com32.cs_bounce; int i; memset(sectorBuf, 0x0, 512); // XXX MARK 1

Attempts to load *.lkrn images were failing with "Not enough memory to load specified image". These images have the su_ramdisk_max header field set to zero, and the code in core/runkernel.inc was limiting MyHighMemSize too early (before the load_high call used to load the main part of the kernel).

Hi, We are using pxelinux at my company to test our product. And there are limitations that we have hit in the past w.r.t. the max length of a path, or the max length of a module name (in mboot.c / mboot.c32). We've used workarounds in the past, and reorganized the directory structure, but we face that problem again. Out of the 128 / FILENAME_MAX chars that can be used, 110 - 120 go to the
