2 *
3 * Description: Autoprobes the os2krnl file and os2krnl[*].sym files.
4 * Another Hack!
5 *
6 * 16-bit inittime code.
7 *
8 * All data has to be initiated because this is 16-bit C code
9 * and is to be linked with 32-bit C/C++ code. Uninitiazlied
10 * data ends up in the BSS segment, and that segment can't
11 * both be 32-bit and 16-bit. I have not found any other way
12 * around this problem that initiating all data.
13 *
14 * How this works:
15 * 1. parses the device-line parameters and collects some "SysInfo".
16 * 2. gets the kernel object table. (elf$)
17 * 3. finds the kernel image and scans it for a build number.
18 * 4. locates and scans the symbol-file(s) for the entrypoints which are wanted.
19 * 5. the entry points are verified. (elf$)
20 * 6. finished.
