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...

Hi, I want to know where is the code for int 22h handler which is used to handle syslinux api's. -- Sincerely, H.R.Tavakolli

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...

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. Implementation and documentation are derived from Int 22h AX 000Eh. There may be a way to be more efficient (with the push/...

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.mandriva.c...

...e time. I'm experimenting with VESA for this... but my real questions are: How do I boot a Linux kernel from a COMBoot (.cbt) program ? Supposed I have syslinux.cfg that looks like this: DEFAULT menu LABEL menu KERNEL menu.cbt LABEL linux KERNEL kernel.bzi Do I have to use AX=0003h, INT 22h with a C-string like "linux vga=317" in ES:BX or "kernel.bzi vga=317" ? Should I return from my VESA mode into normal 80x25 textmode (I'm trying to hide as much from Linux as possible simply for aestetic reasons ;-) The second question is about open file, AX=0006h, INT 2...

...ase DC=DomainDnsZones,DC=domain,DC=local and Attribute isDeleted=TRUE. There are about 80000 outdated entries whom i plan to delete. 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~
