<html><head></head><body>The 128k thing is physical memory, which is sonething else than size of the disk. There is an option in simh in the config to explicitly tell how large disk you want. Check the documentation. <br>
<br>
Use a disk of at least 1g, and we can move on to the next problem, which is going to be the number of file headers on the disk, unless you read that manual I gave the link to.<br>
<br>
Easy howto pages on the internet are nice, but sooner or later you need to read the docs and understand what you are doing.<br>

This means that the disk you are running from (DU0:) does not<br />
have enough free space for RSX to allocate a checkpoint file.<br />
</blockquote>
<br /></span>
Ah! Yes, of course. Thanks for that, Alan. Didn't even think about the possibility that the disk would be that small, since he was using MSCP.<br />
<br />
Ray, start over, and create disk image files that are larger.<span class=""><br />
<br />
<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Start over and tell SIMH to make DU0: (rq0) larger. I would<br />
suggest at least 32 MB if you plan to do anything useful with<br />
the system. Don't go above 500 MB, however, as the ODS-1 disk<br />
structures can't handle anything that large.<br />
</blockquote>
<br /></span>
No, ODS-1 handles larger disks fine. The limit is 8G. If you go above that, there is no harm, but the disk will just be truncated to 8G anyway, so no point in going larger.<br />
I would suggest something around 2G or so, and you're set for life.<br />
(Personally I run with four 8G drives, but then again, I'm not exactly normal when it comes to RSX...)<span class=""><br />
