- Subject: A Win 3.1 beta success story.
-
- Hi! I bring good tidings to many of you. I have finally succeeded (it
- took many reformats) to get the GA + SP + Win 3.1 + 800x600x256 +
- seamless in one ball of wax. My graphics card is a Diamond Speedstar on
- an 8mb 486/33. The good news is that I got word for windoze, pagemaker,
- tetris for windoze, clock and Excel all running seamlessly with only a
- 4mb swap file!!!! It was fast. I don't know how but it was fast. The
- steps I followed were as below:
-
- 1. Install The service pack. Reboot
-
- 2. Immediately after this, install the win 3.1 beta as on the beta. let
- it switch you back to standard vga if it wants.
-
- 3. before rebooting, re install the service pack again. and install
- the new hires drivers again.
-
- 4. reboot.
-
- 5. edit your path in the autoexec.bat file.
-
- 6. edit your system.ini file to reflect the changes that the service
- pack made in the win 3.0 files. there are 2 changes, display.drv and
- svgasomething.drv and those lines should be copied from the new 3.0
- .ini file. Please note that before hand win 3.0 has to be installed for
- this to work.
-
- After this, you should have a fully working 3.1 system with
- everything works. I stole most of this stuff from Alok Dhir. Thanks
- Alok.
-
- Good luck for the rest of you. MOST IMPORTANT, DON'T FORGET TO BACKUP
- THE DRIVE!!!

- Last night I ftp'd a file from ftp-os2.nmsu.edu called "pspm.zip" or

- Subject: Is Shadow RAM a motherboard or a bios feature? Help
-
- Greetings,
-
- I have a 386sx with AMI bios on it. QEMM's analysis indicates that it
- could get only 144K out of 384K available Shadow RAM. The 240K which is
- lost is almost equal to the sum of video RAM, video ROM, disk ROM, and
- BIOS ROM. I am desperately trying to find a way to get back the lost
- 240K of memory.
-
- The BIOS setup lets me enable or disable shadow RAM/ROM. No matter
- what option I use, I still loose 240K of shadow RAM. It seems to me:
-
- 1. The way (my?) motherboard is designed, there is always 384K of
- Shadow RAM (provided I have atleast 1M of memory).
-
- 2. If there is any bios RAM/ROM detected, the corresponding memory RAM
- region is automatically set aside for shadowing.
-
- 3. If we enable shadowing via BIOS, this region is used. If we disable
- shadowing via BIOS, this region is unaccessible and is wasted.
-
- The bottom line is, the more board RAM/ROM I have, the more memory
- RAM is wasted if I disable shadowing.
-
- Is this logic true? Or am I missing something?
-
- Another question: QEMM manual says that it recognizes Shadow RAM if the
- chips are manufactured by so and so companies. To my understanding,
- memory chips are passive elements (besides address decoding part). What
- exactly is the role of a memory chip in shadowing? Do I need to replace
- my SIMMs to remove shadowing completely?
-
- Thank you for your help.

- Subject: More Than You Wanted to Know About Distinctive Ringing
-
- [This note is from the TELCOM Digest, a moderated group on USENET.
- Because of the numerous users that have more than one piece of
- equipment on a single line, and given the difficulties figuring out
- WHICH piece should answer the ring, I thought is was appropriate to
- include in the Info-IBMPC Digest. gph]
-
- Lots of responses this time, as well as finding some old messages I'd
- lost. There are a few ??? still to be filled in.
-
- -- What is Distinctive Ringing?
-
- It is a telephone service that assigns several different phone numbers
- to the same line. Its true name is "Multiple Directory Numbers Per
- Line With Distinctive Ringing". Each number rings in a different
- cadence (single, double, and triple ring) so you can tell which number
- the caller called. The maximum number of numbers per line varies by
- telco, but can be as high as four. You can think of it as a party line
- where all the parties are you.
-
- The price is usually quite low: around here it's $3/month for the
- second number and $2/month for the third. You generally have the
- option of listing the extra numbers or not. (Note to Massachusetts
- customers: NET orignally said I had to pay extra to have them unlisted,
- but the DPU persuaded them that they were mistaken.)
-
- -- What is it good for?
-
- All sorts of things. One use is for people with home businesses, so
- you can answer one ring "Hello" and the other "Thank you for calling
- Bagel-tronics." Another is to share a single line among several
- devices such as faxes and modems. For this use, you'll want a ring
- leader, below.
-
- It is also useful as a way to defeat Caller ID. The C-ID number sent
- on outgoing calls is always the first number so you could assign the
- first number to your modem, or let an answering machine pick up calls
- to the first number and tell your friends to call the second number.
-
- Some allege that it's useful to distinguish between calls to parents
- and calls to teenage children, but given the way teenagers use the
- phone (call every possible number where a friend might be and talk for
- hours) it's no substitute for a second line.
-
- -- Can I use it as a fax switch?
-
- That's what I use it for. I find it works better than the usual fax
- switches. It doesn't depend on answering the phone and listening for
- fax tones which not all faxes generate, so it never guesses wrong.
- Besides, you get a separate fax number which looks much more official.
-
- -- What happens if I also have call waiting?
-
- When a call comes in, the beep is in the same pattern as the ring, so
- you know which number it is. At least, that's what's supposed to
- happen. Apparently, they sometimes forget to set up the beeps right.
-
- -- How do I order it?
-
- You call up the business office, of course. For some reason, each
- telco gives it a different name. The ones I know are:
-
- NYNEX Ring Mate
- Bell Atlantic Identa Ring
- Southern Bell Ring Master
- Ameritech ???
- SW Bell Personalized Ring
- US West Custom Ringing
- Pac Tel not available, see below
- GTE Smart Ring
-
- Technically, distinctive ringing can be installed on 1A and newer AT&T
- exchanges and other modern units. A software upgrade is required (it's
- almost but not quite the same as a party line) so there are many areas
- in which it's still not available even though the exchange would seem
- to support it.
-
- Note for Pac Bell customers: Pac Tel has a service which they call
- "distinctive ringing" which is completely different. Their service is
- a home centrex which rings differently for inside and outside calls.
- If you try to order distinctive ringing, be sure you know what you're
- getting.
-
- -- Can I automatically connect to different devices for different
- rings?
-
- Yes. That's what a "ring leader" does. It is a box that has a modular
- cord that plugs into the phone line and several modular jacks into
- which the devices plug. When the phone rings, it listens to the first
- ring cycle and then connects to one of the devices depending on which
- ring pattern it was. The ring leader itself never answers the phone --
- it just connects to a phone, fax, modem, etc., which answers the call
- normally.
-
- For outgoing calls, ring leaders act as exclusion units and only let
- one of the devices connect to the line at a time. Excluded devices
- hear either a busy signal or a silence.
-
- Many vendors sell ring leaders. Here's a summary of the ones I know
- about, along with the names of the people providing reports.
-
- I have an Autoline Plus fro ITS in Endicott NY. +1 607 754 6310. It
- connects up to three devices. Mine has been entirely reliable. I paid
- about $80 but the price is more like $120 now. (John Levine
- <johnl@iecc.cambridge.ma.us>)
-
- Misco now has a unit that will do just that. It is called the Ring
- Decipher (misco part #fl-3622). The only other identification in the
- ad is "ASAP RD-4000". I'd like to know who makes it, and alternate
- sources. Supposedly, it will provide a standard ring signal on any one
- of the four outputs determined by the incoming ring pattern. Price
- $99. (Bill Petrisko <petrisko@evax2.engr.arizona.edu>)
-
- My first Lynx Automation box didn't work but their beta replacement
- worked. Four pattern model. I bought another one that my brother had
- problems with but I haven't hooked it up here yet so I dunno. I notice
- that Lechmere [local discount department store] is selling the two line
- Lynx at a nonoutragous price ($69 or $79 which is about what Lynx
- charges direct. (Bob Frankston <Bob_Frankston@frankston.com>)
-
- I use a ASAP RD4000 Ring Decipher made by Command Communications Inc of
- Aurora CO. It cost $100 at a trade show. It decodes four different
- patterns. When one of the devices has the line, the other devices get
- a busy signal if they try to access the box. It has worked flawlessly
- for the last nine months.
-
- I had a bad experience with a box called RingMaster made by Lucas
- Technologies of Beacon NY. It failed repeatedly and the maker wouldn't
- do anything about the problems until I cornered them at a trade show
- and made a large noise. They bought the box back for $100. I had only
- paid $80! That was the only good experience with Lucas' RingMaster.
- (John Adams <johna@a-k.boston.ma.us>)
-
- The call route box (avail from Home Automation Lab at 1-800-HOMELAB) or
- the RD1000 from mailorder (this is the one I have) doesn't even pass
- ring voltage to the connected lines until after the end of the first
- ring and it has determined which number was called; therefore, you
- never even hear the phone ring unless they are calling the authorized
- number. (Carl Neihart <neihart@ga.com>)
-
- Black Box's September 1992 catalog lists a product called DRD-4 that
- automatically routes distinctive ring services from one incoming phone
- line to up to four devices. $ 139. Phone 1-412-746-5500. (Marc Kozam
- <mlksoft!kozam@cs.umd.edu>)
-
- -- Can I build my own ring leader?
-
- Probably. Several people expressed interest in coming up with a
- design, but nobody's told me about one yet.

- [TELCOM Moderator's Note: All those names can be confusing. Ameritech
- (Illinois Bell, at least) says 'distinctive ringing' is when your CO

- cause your phone to ring with a special cadence to let you know (for
- example) the boss is calling, or your parents, etc. On the other hand,
- 'Multi-line' is the service discussed in John's article where more than
- one number is assigned to a single line with different ringing cadences
- as appropriate. 'Starline' is IBT's 'home centrex' service which
- provides a different ring for calls from within and without your
- premises. I use my 'Multi-line' service as a way for my 800 numbers to
- ring in. The two short rings tell me it is my nickle paying for the

- Subject: MSDOS Descriptor Table Limitation Problem
-
- I'm a fairly new MSDOS & MS Windows user and I'm not use to being
- limited in certain types of memory usage. My problem is the following:
- I'm creating a linked list based on the size of information coming into
- my program. My function gets called each time a new node is added,
- which in this case could result in a large linked list structure
- (possibly thousands of nodes). After many GlobalAlloc's and
- GlobalLock's I eventually run out of space in the descriptor table.
-
- I've though about allocating a large block of memory and extracting
- portions of this memory to be used in each new entry in the linked
- list, until such time I need more memory... but I'm not really sure
- how to handle this in the windows development environment. It has been
- recommended that I don't do selector arithmetic...
-
- Any suggestions as well as some sample code would be greatly

- the 'file & directory' level. This is to say, MSDOS should never try
- to read a specific sector...it should instead send a request to my
- device driver to read some portion of a file.
-
- One might say 'just intercept the handle functions sent by the user
- via interrupt x21' -- but remember, this system must work if the user
- does an exec (intr x21, function x4B), for example. With the x4B
- function, MSDOS handles the opening, reading, and closing of the file
- itself, internally. ie: I have no guarentee, and Im pretty sure it
- doesn't, MSDOS would use intr x21, x3D to open the file it was exec-ing,
- x3F to read it, and then x3E to close. It is correct that MSDOS isn't
- re-entrant...in the sense that intr x21 x6C wont use intr x21 x3C,
- right?
-
- I've looked over the device-driver chapter in MSDOS Advanced
- Programming by Michael Young. The device driver in there is far too
- low-level. Is there any way I can make MSDOS use a device driver of
- mine, but on a file/directory level?
-
- Any helpfull info/suggestions/insight via email will be welcome (as
- long as you dont tell me its impossible :)

- I am using Kermit 3.11 (DOS version) on IBM/ValuePoint running
- OS/2~2.0. I did all the settings that I needed for the COM port. I
- lose a lot of characters at 19200, but so much when the speed is 9600.
- However, when I push to DOS, I cannot seem to recover. I run kermit
- from OS/2 full screen window, which loads DOS automatically. I have
- not tried running from DOS full screen window. Should that make a
- difference. I think not because OS/2 automatically overlays DOS before
- invoking Kermit. What do you think? Comments? --

-
- This is what worked for me and, hopefully, it will help you:
-
- 1. Set the ET4000 card using VMODE under native DOS first, making
- sure that the video is correct (check with VDIAG). I have a Gateway
- 2000 CrystalScan 1024NI, but the monitor setting for such didn't
- produce high-resolution graphics correctly. I had to create a custom
- monitor setting to get the video modes in sync.
-
- 2. Re-run the VMODE under a full-screen DOS session, and confirm that
- the settings are the same and everything works fine. For some reason,
- trying to set the card under a DOS session alone would not set the card
- properly, but first setting it under native DOS resolved the problems.
-
- 3. Selectively install the Tseng drivers, checking the SVGA box in
- the install options (even if it is already marked). When OS/2 asks for
- disk 6 or 7, it means the OS/2 GA diskettes. It is looking for high-
- resolution fonts. After running through most all the GA disks, then
- you will pick the resolution and use the CSD display diskettes. OS/2
- will run SVGA automatically.
-
- 4. After installing the video, do not reboot! Open a full-screen DOS
- session, and run the appropriate VMODE statements to set the monitor
- (e.g., VMODE MONITOR, VMODE VESA). (For good measure, you may wish to
- delete the \OS2\SVGADATA.PMI file.) Now, run SVGA ON to save the
- current video settings.
-
- 5. Exit, shutdown, and reboot. The WPS *should* come up in the
- desired resolution.
-
- I hope this works with your system. Good luck!

- Subject: Watch dog timer support on ISA?
-
- I understand that Watchdog timers exist on MCA and (some?) EISA systems.
-
- What I would like to know is if one could somehow enable the watchdog
- functionality on an ISA system.
-
- If it is just a matter of an NMI being generated, I can wire up a push
- button that goes to the NMI line... (OR, if it needs a little more, I
- have tubes full of NAND gates that I could wire up into something
- useful... *)
-
- I would like to wire up watchdog-like functionality so that when I run
- my "CLI / forever: JMP forever"* program, I can continue to work
- without a hard shut down.
-
- (And heck, maybe there's marketing potential for an ISA watchdog
- retrofit...*)
-
- Thanks all.
