Answer» I installed DOS 7.1 onto a WYSE S30 thin client but it won't boot from the IDE flash. Says missing operating system despite it being correctly installed onto an active, primary partition. The problem is with the way the BIOS waits for the OS to start booting then it disables the IDE controller.

So to put WYSE Linux on an S30, just make both a WinCE and a Linux update stick then find the WinCE key and replace the Linux key with it. I'd bet all the older WYSE thin clients are done the same way. WYSE ThinOS is a different beastie. That was the S10 model and ThinOS goes into the BIOS chip. the other models may or may not have a larger BIOS chip and in any case you just can't simply download the latest/last update for it.

I installed DOS 7.1 onto a WYSE S30 thin client but it won't boot from the IDE flash. Says missing operating system despite it being correctly installed onto an active, primary partition.

The problem is with the way the BIOS waits for the OS to start booting then it disables the IDE controller. The Windows CE, WYSE Linux V6 and, XP Embedded for these is coded to work around that or re-enable the IDE.

I have a FreeDOS image someone made for the 64 megabyte module for these thin clients. It boots properly but it's all in French.

Since FreeDOS can work, how can MS-DOS be hacked to work?

I've used computers since 1983, DOS from 2.1, Windows since 3.0.Tried DOS 6.2 yet ? ?...force IDE in BIOS ? ?
