Hello, everyone.
I am trying to better understand the EXECRH function in execrh.asm <https://github.com/FDOS/kernel/blob/66df13c4d867b49558a85929a13432df63cf5ac 0/kernel/execrh.asm> . Could someone help me understand the call being made in EXECRH of "call far[.dhp]"? To where is it calling, and should I have done something in my BIOS or elsewhere to support this call? Additional Details: During boot on my 286 build the system hangs during the kernel loading, where a call to EXECRH is eventually made. I don't believe this is a FreeDOS issue, but likely an issue with my BIOS. Possibly, I need to populate some table structure in memory with system or disk information that I'm failing to populate, or I have an issue with one of my interrupt handlers for INT13H disk services. The leadup to the lockup goes something like this: * The kernel starts its loading process. * . * The truename() function [newstuff.c] is called during the kernel load/processing. * The truename function then calls media_check() [fatfs.c]. * The media_check() function calls rqblockio() in the same file. * The rqblockio() function then calls execrh() [execrh.asm]. If it's helpful, I posted some print screens of a debug build bootup and some additional information here <https://www.rehsdonline.com/post/troubleshooting-freedos-boot-on-my-286-sys tem-hangs-on-execrh-call-in-kernel> . If anyone has any guidance, suggestions, pointers to helpful reading material, etc., I would be grateful. Thank you! Rich
