Hi, I would like to use INT22h, function 000Dh, but I found that it is disabled in vector table: in core/comboot.inc: int22_table: [...] dw comapi_err ; 000D clean up then bootstrap [...] The code of this function is present in this file (comapi_chainboot). Why this function is disab...

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 3.51

From: Gene Cumm <gene.cumm at gmail.com> COMBOOT API: Add calls for directory functions; Implement most only for FAT (SYSLINUX). Uses INT 22h AX= 001Fh, 0020h, 0021h and 0022h to prepare for the COM32 C functions getcwd(), opendir(), readdir(), and closedir(), respectively. INT22h, AX=001Fh will return a valid value for all variants. INT22h, AX= 0020h, 0021h, and 0022h are only implemented for SYSLINUX while other variants will call comapi_err for these 3.
