I have a Leading edge 486sx25 with 4 Megs of RAM that are in the forms of   4 1 meg SIMMS.  Each SIMM has *two* chips on it. They are manufactured by   Samsung and are 80ns.  A salesman told me that the leading edge CPC-2300   motherboard has the extra parity bit built in and reccomemnded I use MAC   SIMMS. I tried using 4 Megs pulled out of a Mac SI (these are 8 chip   SIMMS), but I got too many windows protection faults and parity errors. I   guess I should use the same SIMMS as the ones I have, but I can't find   any!! Most of the places I have called carry only 3 8 or 9 chip SIMMS.  So if anybody knows where I can get memory that is good with my computer   or if you have any suggestions at all, please let me know.  Any help is truly appreciated.  -Eric
I'm planning to buy a computer and I like TC's ads.   Can you tell anything about the company and their computers?  Also, if anyone has a company they  would prefer, please let me know.  Thanks.
I would like advice on how to configure my 486 to accept: - Com1 + Com2  (currently on IRQ 4 and 3) - LPT1 (IRQ7) - Bus Mouse (IRQ5) - Sound Card (no idea what to do - can be set to any) -  using IRQ2 for Bus MOuse gobbled up too many cycles, and caused loss of communications with floppy disks, and a few other  problems.  I could, I suppose, switch the 2 com devices externally, and disable the second port on the Super IO card, but I really want to  have them both available.  COuld the sound card use IRQ2 without horsing up the works?  All replies apppreciated - and I only just subscribed to this newsgroup - I assume there is an FAQ somewhere (rather, I'm sure someone will tell me about it....)

Can someone throw >some more informed light on this issue? >[...] >Michael Hamilton  Some motherboards support VL bus and 50-DX CPU.  There is an option (BIOS I think) where additional wait(s) can be added with regard to CPU/VL bus transactions.  This slows the CPU down to a rate that gives the VL bus device(s) time to 'do their thing'.  These particular wait(s) are applied when the CPU transacts with VL bus device(s).  You want to enable these wait(s) only if you are using a 50-DX with VL bus devices.  This is from reading my motherboard manual, and these are my interpre- tations.  Your mileage may vary.  Strictly speaking, VL and 50mhz are not compatable.  And, there is at least one 'fudge' mechanism to physically allow it to work.
Hi fellow netters,  does anybody have any info on Tseng Labs ET4000 VLB card: price, speed, compatibility with existing and up-comming softwares, performance compared to others cards ( is it an S3 based card ?)....

I ran out of time on my last reply to this string and I don't know if it was sent or not but. I have never heard of anyone that had to return something in the 30 grace peried that had a problem at all with Midwest Micro. They may of thought that you didn't know what you were doing and suggested how to correct the problem. But it sounded as you didn't give them much of a chance to correct things at all. The fact that the PPI worked okay for you is because it is setup more for the no nothing user that can't understand the instruction and the commands to configure it to his/her system. When you find out things like the fact the the EC led that looks like you have connected to another EC modem, doesn't realy say that. But that it only tells you that you have EC turned on, on your modem. I think that these LED are nothing more that just light to hype up the product. Just like I bet someone took home a few extra $$$ in the last year for giving the PPI modems the PC-Magazine award of the year. Not so for the stash (12) of them that I saw on my test bench. I could go on for hours at no end as to all of the problems that I found with the PPI modems but I will try to control myself. I will not even go into the 6 weeks it took PPI to credit my card back for the modems after they had received them back...no I will not go into that one nor will I go into talking to the parent co. co from Hayes. I'll just say I hope you like your new modem and maybe someone that can understand how to setup a modem will get the one that you sent back, maybe a good friend of mine I hope!

When it comes to local dealers:  - Have fun getting consistently good support.  Most of their "techs" are re-treaded salesmen, not trained technicians, with a high turnover rate.  - Have fun getting in-warranty work done quickly and courteously.  - Have fun getting out-of-warranty work done cheaply, or even done period, unless you are on a paid service contract.  Having been both a service technician, and a service manager, at a ComputerLand franchise and another retail computer place, I know what I'm talking about.   I also know the "local service" scam that retail computer dealers like to push when they're selling.  It's that same old song that car dealers having been singing for years -- "Buy from me and you'll get good service. We always treat our customers right!  Buy from my competition and you'll be sorry if you need service."   Experienced mail order buyers know that there are some mail order companies that give excellent service, including overnight replacement parts,  on-site calls, etc. There are probably some local dealers that can give you good service, too. But if you think all local dealers give consistenly good  service, you are wrong.  I have many anectdotes to prove my point,  but I'm sure there are others on the net can do a better job than I can.

I'm using int15h to read my joystick, and it is hideously slow.  Something like 90% of my CPU time is being spent reading the joystick, and this is in a program that does nothing but printf() and JoyRead().  The problem is that a lot of programs trap int15h ( like SMARTDRV ) and so it is a slow as hell interface.  Can I read the joystick port in a reasonably safe fashion via polling?  And that isn't platform or clockspeed specific?  Thanks,

Hello All!  I recently acquired a CD-ROM drive, a Mitsumi (mfg. Feb/93)   [Hey, it was free :-)   ]    I'm quite pleased with the performance, but it seems to crash a lot when I use PLAYCD.EXE that came with it a DESQview 2.31 - Thoughts?  This mainly happens when my BBS is running in the background and I load the program up.. If I load the program, it doesn't crash, and I start the disk, stop the program and start the BBS its OK, but otherwise I have big problems.. (IE, they can only be solved with a cold boot).  If -anybody- can mail me to help me, I would be eternally grateful  (unfortunately, my feed to this group is a little unreliable so I would appreciate  if you could mail, but by all means, post it too because I'm sure somebody else   would like to know...)  Cheers, Wes

Hai,  In a few days I'm going to buy a new motherboard with local-bus(ses). It comes with a Cirrus Logic VLB card which has 2Mb RAM onboard. It can do true-color but I don't know what type of card it is. I read that Cirrus Logic cards aren't exactly the fastes around.  My old system had a TSENG 4000. I was pretty pleased with it, so I consider buying a W32/TSENG card. I'd like to know a few things:  	- How is the speed/performance in DOS/Windows/Unix/OS/2 	  Graphics & Text (also compared to S3 cards for example) 	- What resolutions (including no. of colors) does it 	  support (text & graphics) 	- How many RAM can be installed and what type of RAM 	- Compatibility with old TSENG 4000 	- Support in software  If anyone has any experience with this card (good or bad) I'd like to know. If you have a better alternative than the W32 please tell me about it.   For the people in Holland: Kan iemand me misschien vertellen waar de W32 in Nederland te verkrijg is? Het liefst in de omgeving van Amsterdam!
Could someone please tell me what the dip switches on the back of the AST Hot Shot 286 accellerator card do?

Anybody seen the date get stuck?  I'm running MS-DOS 5.0 with a menu system alive all the time.  The machine is left running all the time.  Suddenly, the date no longer rolls over.  The time is (reasonably) accurate allways, but we have to change the date by hand every morning.  This involves exiting the menu system to get to DOS.  Anyone have the slightest idea why this should be?  Even a clue as to whether the hardware (battery? CMOS?) or DOS is broken?

Thanks.     A program in the archive keymap00.zip on simtel and mirror sites in the  msdos/keyboard directory will do this.  It is written in assembler and it  best if you have a compiler to create a new keyboard map.  It is possible,  however, to use a binary editor to edit the provided compiled keyboard  driver if you do not have a compiler.  I used hexed100.zip, also available  on simtel.  Simply serach for the codes 00 01 02 03 to locate the biginning  of the "normal" keyboard map.  Then swap the codes for the keys that you  wish to swap.  See the keyboard directory of simtel for programs that report  the scancode for each key to you (some bios programs also have this info).

There would be no problems as long as the OS didn't set up a DMA transfer to an area above the 16 mb area (the DMA controller probably can't be programmed that way anyways, so there probably isin't a problem with this)
Re: Problems with S3-initialization  As described the manual the following steps must be done for th initialization of the S3 card.  InitDisplay; 	(*BIOS-Call 		with AX-Reg = 4F02H 		with BX-Reg = 105H for 1024 x 768 x 256 resolution 		Interrupt 10H *) Unlock Register Lock 1 (CR38) 	(* For access to S3 Register Set *) Unlock Register Lock 2 (CR39) 	(* For access to Syst. Control and Syst. Extension Register *) Unlock Graphic Command Group (CR40) 	(* Set Bit 0 to 1 in Syst. Configuration Register *) Unlock Advanced Display Functions 	(* Set Bit 0 to 1 in Function Control Register *)  After these operations the FIFO-stack of the S3 should be empty. When we watch the status (Graph. Proc. Status), we always get the value 0FH instead of 0H. Full would mean 0FFH (8 places occupied), empty would mean 0H (0 places occupied).  It is possible to read this register in two different ways.  Both times we get different results.    Our machine is a 486 DX/2 with EISA bus and a S3 86C805 local bus.   --> any ideas?

There are no standards for PC COM ports above COM2.  While there are "de facto" standards for COM 3-4, they are not guarenteed to work.

Does anyone know if there are any problems (or if it's possible) adding a third hard drive(scsi) to a dos pc.  I currently have a 386 pc with  Future Domain scsi board  and  2 Maxtor  scsi  drives  installed.  They work great, I haven't had any problems!  Well, now I want more disk space and went out and  got   another (larger)  scsi   hard  disk  thinking all I had to do was add it to the chain(50pin ribbon  that  has  3  connectors)   and   run the   fdisk   program   to format/initialize the disk.  That didn't happen.  When the pc boots, the  scsi  prom   shoots back   the  devices   that   are  attached  to  the board[target 0/target1/target2].  All three disks are seen.  When I run the dos fdisk program to format the disk, I choose to select another  disk(option  5(dos6)) and voila, it's not there. The first two disks show up no problem, but the  third  disk  is no-where to be found....    ARGH!  Ideas anyone?????

First of all, thanks to those of you who responded, both here and via e-mail. The tips didn't pan out, but it was good hearing from you.  Now, following up to my earlier post: [...] : Disk controller:  Acculogic sIDE-3 2 hard/2 floppy IDE controller :   Jumpers:  All defaulted (shown as *):   :     Normal IRQ*/delayed IRQ     Primary*/secondary floppy address :     Single*/dual speed floppy   Primary*/secondary IDE address :     Precomp = 125ns*/187 ns     IOCHRDY not driven*/IDE drive controls IOCHRDY [...] : Other cards:  (didn't check brand) 2 Serial/1 Parallel adapter : 	      Logitech Bus Mouse adapter : 	      Roland MPU-401-compatible MIDI interface  : 		Configured with default IRQ 2, mem address 0330  I opened up the box and removed all the "other cards" above.  No help there. Then, not having anything better to try, I changed Normal IRQ to Delayed IRQ on the disk controller (didn't make any difference) and IOCHRDY_not_ driven to IDE_drive_controls_IOCHRDY (also had no effect).  So I put  everything back to the way it was and re-installed the cards.  I then unplugged the floppy drive cable from the disk controller.  Voila!, the PC booted from power up, although it seemed to take several seconds  before the first access to the hard disk.  Plug the floppy cable back to the controller and the original (non-boot) behavior returns.  O.K., with this additional information, does anyone in netland have any  words of wisdom for what's going on and how I should deal with it?

From what I've seen in coursework, most CPUs never actually "idle".  They will continue to service interrupts, etc., etc.  The clock will always be running at n Mhz no matter what it's doing.  I suppose depending on the instruction, the CPU may use circuitry which has more transistors than other instructions, but if you consider the additional heat generated by only a handful of additional, tiny resistors and then spread that heat dissipation over the CPU's packaging, the change in temperature to the immediate environment (ie. the surface of the package) will be negligible.
