This number could be reduced +by a smarter treatment of library functions, but such an effort hasn't +yet been done. + +Also, the kernel debugger cannot read a "-rom" linked jensfw.exe image. + +So, for the time being, this is how to link the kernel debugger stub +into the firmware: + +1. Make space for the debugger stub by not linking in some code. Easy +targets are NTFS, CDFS, or EISA bus configuration. Currently the +code is set up for the victim to be the NTFS filesystem. + +2. Edit linkjens.rsp to remove the modules from (#1) from the link list. + +3. Add these lines to linkjens.rsp: + + obj\alpha\fwkd.obj + obj\alpha\kdstubs.obj + ..\..\..\nthals\hal0jens\obj\alpha\jxport.obj + +4. Add this line to the end of linkjens.rsp: + + \nt\private\ntos\obj\alpha\kd.lib + +5. Copy linkjens.rsp to linkjens.tru. + Copy linkjens.rsp to linkjens.dbg. + +6.
