    I’m not sure if this is something that is fixable or if it’s just a fault of the firmware, but whenever I try to set the display resolution to 1280×1024 on an S30 running CE 5.0 build 588, the WinTerm will crash horribly during boot.

    Right after the yellow WYSE/Windows CE splash screen, when the progress bar reaches the end and the CE desktop is supposed to load, I am instead greeted with a black screen that has a distorted grey-coloured version of the previously mentioned splash screen “shoved” over and squashed in the left side of the screen. At this point, the S30 freezes and the only thing I can do is turn it off and do a G-key reset.

    I noticed that WYSE just released build 590 in the last couple of days, and I downloaded it hoping that they fixed the issue, but it’s still there and just as bad as ever.

    I have tried this on about 4 different S30s now, each from a different date of manufacture, and they all have the same problem. I have also tried different colour depths and refresh rates, but it doesn’t change anything. Just in case it has any bearing on anything, the monitor I’m using is an NEC AccuSync LCD72VX.

    Has anyone else encountered this issue? If so, is there a fix for this, or am I going to have to wait for the next firmware build and hope that WYSE fixes it by then?

    Can you check the product number on the units if it ends with an “L” or not?
    The “L” indicates if they are the newer RoHS compliant ones or not.

    Some of them are newer ones made in 2008/2009 which are RoHS compliant (the part number ends in 01L), but some are older S30s made anywhere from 2005 to 2007.

    I believe the three S30s I tried the new firmware on were made in mid-to-late 2006/early 2007

    Edit: I tried resetting the BIOS settings to their defaults on the non-RoHS compliant S30 unit I am using for testing, and now the display works properly at 1280×1024. When I reset the settings to their defaults, the video memory allocation was changed to 9 MB, where it was set to 6 MB before. I checked a few other S30s we have in production, and some of them had their video memory settings set as low as 4 MB.

    Was the problem simply caused by there not being enough physical memory allocated as VRAM to handle the larger resolution? If so, is there any way I can configure this setting remotely with either a registry setting or a script? I know it’s possible to set the boot device order in the BIOS using the CE registry, but I’ve never tried for the video memory allocation.

    Yes, the problem is definitely the amount of video RAM.
    AFAIK there is no way to adjust the video memory remotely. You should contact Wyse to get a custom script.
