Sheesh, am I the only one working on this thing?
I've made a lot more progress. I managed to mount the WP's DOC in my Linux system by building a custom kernel and using M-Systems' lousy evaluation board. I can now get to the entire file system and read/write anything I want. I've got a backup of the whole thing in a TAR archive, just for safe keeping.
I gave up on using the serial port for the time being since no one seems to have the time or ability to figure out the pinout.
I have tried some more to get a shell running on the console with minor success. I can prevent the X system from starting and can now get it to accept keyboard input. I cannot get text to go to the screen, though. I suspect this is due to the kernel putting the screen in some graphics mode in order to draw the boot progress bar. It'd be great to have some simple utility to put the screen back into standard text mode.
I tried to get the screen back to normal by starting X (with xinit) and then exiting. X did start and stop well enough, but it left the screen in some other graphics mode still. It might be the same mode as when I started, just saved and restored by xinit.
I installed and ran a supposed BIOS password cracker called cmospwd. It didn't help. I can't even tell which particular version of the Phoenix BIOS this thing's running. Any ideas? Any good BIOS password crackers for it (that run under Linux or have source code)? If we can get the BIOS password, then I'm assuming we can make a drive connected to the IDE connector the boot drive and run anything we want.
I've got the whole WP application as a set of Java JAR files that I'll play with on another system. I would like to figure out the setup password algorithm so we can get into the settings any time we want.
What I'll probably do, especially since there's very little interest here, is build my own 2.4 kernel with USB support and try to get the USB ports to support ethernet. Then I'm going to use it as a bed-side or couch-side silent terminal on my home network. It'd be nice to have a browser near the TV for TV Guide, game show play-alongs, etc.
Does anyone still care?
