[ISPDr]

G'Day,

Okay, after reading this formum I went out and grabbed as many Snap Servers as I could from ebay (2 x 4100 and 2 x 1000) now. I liking hacking thing... ;-) I have had a REALLY good play with every thing in the 'debug' section.... the two drive mirror is a gift on the 1000s! (Raid 5 isn't an option - even with 2 disks - it needs 3 drives minimum). But! To get a mirror, all you have to do is:


1. Make sure you have the latest snapOS on it (3.4.803)
- its the same version on all of the < 4500s (bonus)

2. Go into debug mode

3. bios unlock (this enables perm changes to the bios)

4. bios model 0 (this make it think you now own a 2000.....)

5. bios lock (just to be sure etc)


Done.... go to the disk utilties section.... and bing there you go.... you should now have the 'Configure Disks' option as of course, you now infact have a snap 2000 - which comes standard with two disks ;-) Enjoy!



Now.... if anyone know where to change this:

debug
info nvram

NFS: ENABLED
HTTP: ENABLED
Telnet remote console: DISABLED (0) <<<<<<<<<-------
RCP server: DISABLED (0)
BOOTP server: DISABLED
HTTPd Port: 80
SMTP Port: 25
SCSI Termination: INTERNAL, external devices illegal.
Protocol Daemons: 32
Raid Cache: 0
Raid Threads: 0
Current Code Page: 437 = US English
File System FSync: ENABLED
FileSystem Full Alert: 90%


... then I would be truly greatful! Clearly the units have a lot more of the OS in them than many first thought. So, If you know how to make the Telnet program action PLEASE let me know ;-)


BTW too anyone a bit scared to play with debug.... I wouldn't worry too much. I have pretty much changed every option I could get my hands on and still haven't managed to break it yet! Only two hints ive found:

1) keep the bios lock on unless you know what your doing
2) the bios flup is one to stay away from (somthing to do with OS upgrades... run it and you go to reset the box to factory defaults to get it back).


Ahhh one other one I did find that would be _really_ good for everyone - expecially 2200 / 4000 / 4100 owners - 'QDL - Quick Dir Lookup'. By default this will be turned off (and I dont think there is a way to turn it on other than debuf). Essentially this 'pre-caches' all of the files in the directory structure, so that any reads from client boxes grab it from the cache and not the drive - this REALLY speeds up clicking through directory structures through windows (an order of magnitude if you have 1000+ files in there). Its easy to do.... from debug mode:

qdl start
qdl scantree /0 0 (/0 for first 'logical drive' /1 if you have a 2nd etc)
qdl buildtree /0


Thats it - your directorys should scream along now!


Finally, if you have a 4000 / 4100 (might be the same for the 2200 - but I haven't seeon one). Take the existing sim out - 64Mb, and replace it with the biggest one you have - ive had them running up to 512Mb. This will REALLY help disk performance as the OS sees this and uses it to increase the 'cache ramsize'.


Hope this helps everyone - im totally stoked with the units (just after a cheap 2200 - hint hint) to complete the collection and Im done! Software wise love it too- only two things... id love to know if anyone has the telnet going ;-) And if anyone has a single bloody Java app running it! Ive looked everywhere but, just cant find anything a) worth running on it b) offered by anyone other than snap (err if anyone knows any helpful hints on the S2S key, then please let me know).

This has been a great forum, would love to hear from anyone that knows anymore:
1) Hacks about the OS (especially debug mode)
2) If anyone knows much more about the hardware a) what is that other ide-looking connectots labeled 'isp'; b) what goes into the two 20 pin connectors (currently not soldered in).


If anyone has any other questions on some of the debug bits, please let me know - have spent way to much time playing with it already ;-0



Enjpoy.
