inconsistent Int 22h local boot
I have a Dell 1435 system that will not respond correctly to a com32 call to Local boot Int 22h AX=14h DX = 0 This call should not return. It should unload the PXE+UNDI stacks and continue the boot process with the next boot device. This call is working fine for me on an HP DL360G2 and on a Dell PE 850. But, on this Dell 1435 the call is returning from the Int 22h. I am using syslinux 3...

Problem with opening a file
Hi folks, I've got a problem with COMBoot (16 bit) in SYSLINUX 2.06: while the write string call (ax=2, int 22h) works just fine, the open file call (ax=6, int 22h) does nothing at all. Calling that function doesn't modify any register, and doesn't modify the carry flag. I then modified comapi_open in comboot.inc so it sets ax to some value and recompiled SYSLINUX, reinstalled it in my disk image...

INT 22H AX=000Ah, CL=9 and __syslinux_get_derivative_info()
comboot.txt says to set CL=9 "to get a valid return in CL for all versions". The code in __syslinux_get_derivative_info() doesn't set it. Is this comment obsolete? Looking at comboot.inc suggest this because P_CL is set to SECTOR_SHIFT for all derivatives but pxelinux which does set P_ECX to MyIP. - Sebastian

Int 22h AX 001Eh for now as it appears that the COMBOOT API is designed to be strictly sequential. The API gets extended but only implemented (for now) for SYSLINUX in ldlinux.asm.

[1/1] [gfxboot] align buffer used to read data from disk to a 512 byte boundary
The COM API provides a function to read from disk (int 22h, AX=07h) which needs a destination buffer aligned on a 512 byte boundary. gfxboot uses this function but doesn't ensure its data buffer is properly aligned. This leads to failures on a few machines (HP Pavillion dv5): gfxboot: isolinux: Disk error 09, AX = 424F, drive FE https://qa.ma...

If I loop over each line in my list and run ldbdel -H DC=DOMAINDNSZONES,DC=DOMAIN,DC=LOCAL.ldb [DN] it takes about an second for each entry so it would take about 22h to delete them all. Is there a way i can speed things up? Thanks in advance achim~

Next, rename the function searchdir to searchdir4any, create a new function called searchdir and move all regular file-specific code to searchdir.
