After having some weird problems with a program of mine, I found this possible bug in GS/OS... If you open a file, write to it, take the disk out and replace it with another one, then try to close the file, you get a mount volume box (assuming your SysPrefs allows it). If you choose Cancel, you get a $20 (bad request) error if the disk isn't write protected, or a $2B (device is write protected) if the disk is write protected. This is really weird since GS/OS has no business trying to write to the disk if the volume name doesn't match. Instead, it should return with a $45 (volume not found), right? Any comments about this or suggestions for a work-around would be appreciated. BTW, I'm using System Soft 5.0.4, but the same problem exists in 4.0.

I believe this is a bug in the ROM 01 SmartPort firmware. I think it's been
fixed in ROM 03.

Well, I'm glad somebody noticed my message :-) Yours was the first reply I got! Is this the same bug as the one that messes with some zero page locations and doesn't restore them, or is this another one? >Henry >-- >Henry Throop >THROOP@GRIN1.BITNET >throoph@jacobs.cs.orst.edu -- David Huang | Internet: daveh@ccwf.cc.utexas.edu | "How much is that hamster UUCP: ..!ut-emx!ccwf.cc.utexas.edu!daveh | in the window?"

Is this the same bug as the one that messes with some >zero page locations and doesn't restore them, or is this another one? I don't know. The only thing I remember about the zero page getting messed up was from a letter in A2-Central that said settting the volume to 0 on a ROM 3 (thus flashing the border instead of beeping) wasn't a good idea if you weren't using GS/OS. Maybe someone from DTS can enlighten us. >David Huang | Henry -- Henry Throop THROOP@GRIN1.BITNET throoph@jacobs.cs.orst.edu
