Summary of this long post: - there's a new utility disk, version 1.21, on the IBM BBS that's just a few days old. - tells how to get the XJ2144 (& presumably other PCMCIA modems) to work across suspend/resume and hibernate transitions (for MS-DOS 6.2/Windows 3.1 at least). After working a bit with my XJ2144, I found a minor problem with resuming from suspend. For some reason, whenever the XJ2144 drivers were installed & I resumed from suspend, my screen would not light up for entering my ROM password. It would come on after I entered my password and the DOS or Windows screen reappeared. Really weird. Not a big deal, but it annoyed me, so I called Megahertz. They were very helpful and sent a FAX pointing me to the IBM BBS and the new Utilities disk. I cross referenced their FAX to my archives of this mailing list, and found nearly the exact same message here (I should have looked at my archives first!). So I called the IBM BBS, and downloaded both Version 1.04 of the BIOS and Version >>>>> 1.21 <<<<< of the Utilities disk (yes, there's a new version of the Utilities disk as of just a few days ago. This version apparently replaces 1.2x. I didn't notice anything in 1.21 that 1.2x didn't already have. I wonder if 1.2x was a test/experimental release, therefore, the x?) I loaded everything up, tried out EzPlay, and removed all references to Mezahertz from my CONFIG.SYS, AUTOEXEC.BAT, and SYSTEM.INI -- they aren't needed any more with Ezplay. I made sure my modem was still working, then tried the suspend/resume test. Boom! My back light is still not coming on. After doing a few more test, I found other problems, such as the PCMCIA not powering up after coming out of hibernate and system hangs when resuming from a suspend while in Procomm for Windows (these might have also been there before - I really didn't get into this level of testing when I hit the back light problem and got the FAX). But I found the trick! I went back into my CONFIG.SYS and deleted all the lines having anything to do with PCMCIA, rebooted, then loaded the 1.21 Utilities again. It added all the PCMCIA lines back to myCONFIG.SYS, and you guessed it, now everything works correctly! I can suspend/resume and my screen lights up for the password entry. The PCMCIA power is turned off on suspend, and turns back on on resume (there is a short pause that didn't used to be there before while I guess it reinitializes the cards). I can use the modem after a suspend/resume! I can even use the modem after a power up from hibernate! It's great! All I can surmise is that the Utilities install program, PCMINSTW, must not have moved all the new files across because it saw the devices already loaded. When I removed the devices, it must have done the install as a virgin install (any other theories?). Summary of what I did (for my 750C running MS DOS 6.2 & Windows 3.1): 1) Loaded Version 1.04 of the BIOS (SY750104.EXE from the IBM BBS or SYS750 on CompuServe). 2) Removed all CONFIG.SYS PCMCIA device entries 3) Removed all MEGAHERTZ entries from CONFIG.SYS, AUTOEXEC.BAT, & SYSTEM.INI (these were left over from running the Megahertz install program when I first got the modem. EzPlay seems to eliminate the need for any Megahertz software on the system -- have card, will travel). 4) Rebooted, then ran PCMINSTW from the Utilities Disk Version 1.21 (UT750121.EXE from the IBM BBS; not yet on CompuServe). Next step -- getting my IBM PCMCIA Ethernet to work. It should be a lot easier now with EzPlay. I need to use it with both Windows for Workgroups 3.11 and with TCP/IP. I'll be loading all this up week-after-next when I return from Microsoft Tech Ed. Any war stories and mine pit warnings would be appreciated before I start. Anyone know what new twist the Ezplay puts on the Ethernet PCMCIA? Should I, or should I not, install what's on the IBM floppy for the card? Ezplay does see the card, but for the moment shows it as not ready. Onward through the fog. Wes
