Apparently-To: john.smith@gravis.com GUS Daily Digest Sat, 6 Nov 93 007 Volume 8: Issue 6 Today's Topics: 256Kx4 DRAM vendor cross reference A potentially stupid DRAM question DosMax?? Where is it?? FYI GUS 206L problem GUS and JP GUS Daily Digest V8 #5 (3 msgs) where is mega-h.zip Where is mega-h.zip??? Standard Info: - Meta-info about the GUS can be found at the end of the Digest. - Before you ask a question, please READ THE FAQ. ---------------------------------------------------------------------- Date: Fri, 5 Nov 93 16:01:37 MST From: tschmidt@pefs1.micron.com (Tom Schmidt) Subject: 256Kx4 DRAM vendor cross reference I have a few updates to the list of vendors that make 256Kx4 Fast Pagemode DRAMs. I am not saying that all of these will work in the GUS because the timing and power consumption of every vendors design is slightly different. Nor have I personally tested each of these vendors in the GUS. If anyone has pros or cons about any of these vendors, or knows of additional vendors parts that work with the GUS, please post them to the digest or E-mail me so that we can update this list and get it into the FAQ. This is only a cross reference list that I put together with a little research into various DRAM data books and the IC Master 1993 master selection guide. For simplicity, I am leaving the speed grade designation off (a -10, -8, -7, or -6 extention at the end of the part number). Manufacturer Part Numbers of 256Kx4 Fast Pagemode DRAMs -------------------- ------------------------------------------ Micron Semiconductor MT4C4256 AT&T M441024 EDI EDI44256C Fujitsu MB81C4256P Goldstar GM71C4256A Hitachi HM514256AP Hyundai HY51C4256 or HY53C4256 Intel 21014 Mitsubishi M5M44C256BP Mosel-Vitelic V53C104 Motorola MCM514256AP NEC uPD424256C NMB AAA1M304P OKI MSM514256 Panasonic MN41C4256 Samsung KM44C256BP Sharp LH64256 Siemens HYB514256 Texas Instruments TMS44C256 Toshiba TC514256BP You may have noticed that the Sanyo part (LC324256BP) has been removed from this list. This was done because at least four GUS users have reported problems in the digest when trying to use them to upgrade the GUS. I also could not find the Sanyo part in the IC Master or other data books, so I am not exactly sure whether or not it is a 256Kx4 Fast Pagemode DRAM. I repeat: I am not recommending any one part type or vendor. _____ ___ Tom L. Schmidt | | / \ Manager - Component Characterization | | \___ Micron Semiconductor, Inc. | | \ 2805 E. Columbia Rd.

It's not silly at all. Yes, these parts do have 1 megabit, or 128Kbytes on them, but you can't easily access them that way. Each chip only has 256K addresses that you can access. The "x4" means that you can get 4 bits at one time from each address. Thus you need 2 chips to get 8 bits (one byte) out at the same time. And when you put these two chips together, you get 256K separate addresses that you can access. So to summarize, there are two pieces of information in 256Kx4: 1) the number of addresses (256K) and 2) the number of bits you get out in parallel (4). Makes a lot of sense once you get used to it. I hope this helps... Burns ------------------------------ Date: Fri, 5 Nov 93 06:14:00 BST From: b.williams44@genie.geis.com Subject: DosMax?? Where is it?? Dear Paolo Colombo, Since I don't know where you're logging in from? I'll try to tell you a little more more about the program and straighten out my post for you. DOSMAX.EXE is a Device Driver which will Maximize the use of low Memory by moving MS-DOS 3.1 or above, system data to upper memory block (UMB) provided by your upper memory manager.(Since I use Dos 6.0 I don't know what you are using and MemMaker is very helpful) DOSMAX.EXE also can move a portion of COMMAND.COM into a UMB instead of the High Memory Area (HMA). This feature recovers space in low memory which is available when DOS is in the HMA. Support is also included for Windows 3.0 and 3.1 , There are also many more features included, too many to go into here.Also Zipped file includes a couple of other programs by the same author. As to where I got it, I stated that I had downloaded it off a Local BBS. And though that it probably was on Internet or Epas, since it is a Shareware program and well worth the registration price.I know for sure it is on Genie (I uploaded it myself) and it is on Compuserve.But are you out of the Continental United States or Canada? If not get in touch with me thru Genie at this Address. B.WILLIAMS44@Genie.Geis.com ,It can be sent thru Internet to this address. If you are outside of the US or Canada, we can work out somehow getting it to you, I hope. I average around 618k Conventional memory ,have Mouse, Sbosdrv and Smartdrive loaded high in UMB. Also it loads around 272k of COMMAND.COM high into UMB.I use a statement in EMM386 line after my Expanded memory #number.It's I=B000-B7FF this uses the system UMB that is set aside for the SVGA and Monocrome Monitor, and adds several UMB's to system.Acually I've ran my SVGA while this was being used for UMB's and I had no problems with the video. This is my MEM/C statement from Dos prompt. Total = Conventional + Upper Memory Blocks MSDOS 15277 (15k) 15277 (15k) 0 (0k) HIMEM 1168 (1k) 1168 (1k) 0 (0k) EMM386 3120 (3k) 3120 (3k) 0 (0k) COMMAND 2976 (3k) 2704 (3k) 272 (0k) DOSMAX 288 (0k) 0 (0k) 288 (0k) SMARTDRV 27280 (27k) 0 (0k) 27280 (27k) MOUSE 17088 (17k) 0 (0k) 17088 (17k) FREE 713936 (697k) 632848 (618k) 81088 (79k) As you can see I have plenty of Conventional memory and quite a large UMB and with out Smartdrive there's even more UMB room.A word of advice Seal Team the newest Electronic Arts release doesn't like Smartdrive. I'm using MSDOS 6.0, no Doublespace, Memmaker of course and DOSMAX.EXE. If you don't have DOS 6.0 but have DOS 5.0, upgrade it's worth it! Also with DOS 6 I can use more than 1 Config.sys and Autoexec.bat by using DOS 6's Batch program it's nice. Also I'm not loading SBOSDRV because Ultramid removes it anyway.

I just thought some of you might be interested in this little tidbit. The Computer Science department at UNC-Chapel Hill, which boasts the fastest graphics computer in the world, and is a world leader in Virtual Reality Research (paraphrased from "Computer Graphics World", March 1993) has just decided to set up a PC at every Head-Mounted Display to act as a dedicated sound server. The GUS will be the card used in these machines. The decision to use the GUS was made primarily because of the 3D capabilities, and the fact that most other cards offering 3D sound were 10-20 times more expensive than the GUS. I thought this was a pretty impressive notch in the GUS belt. ------------------------------ Date: Fri, 5 Nov 1993 12:40:19 +0100 From: Nils Olav Brandstorp Bekken Subject: Re: GUS 206L problem > Date: Wed, 1 Sep 93 01:52:01 PDT > From: zorro%40607.hepnet@Lbl.Gov > Subject: GUS 206L problem > Message-ID: <930901015201.20210e91@Lbl.Gov> > > i have unzip all the disks with the -$ option so i put the label on the > disk infact it put the label 930520 GUS2 on all disks, but when i install it > and i choose the full installation it begin to copy the disk1 then when i > ask for disk2 and i insert it and press return it tell me that it wants disk2 > i press return and it answers with the same thing "insert disk 2 and press RET" Delete the labels from the disks (you know, label a: -> delete current label:Yes) and try again, I had no problem installing it without any labels. If you still can't get it to recognize the disks, use the right labels. I don't remember them right now but I've seen them somewhere. Nils Olav B. Bekken ------------------------------ Date: Fri, 5 Nov 93 14:28:22 MET From: Broderdue Subject: GUS and JP First I want to say that I got my GUS 2 weeks ago, and everything has worked smoothly. Sbos, mega-em, AIL - everything. Great card. Was just wondering if John Smith please could give is a word about Jurrassic Park. He said he was looking into it last week (I think) after hearing that this guy in the UK actually tested a beta with 3d sound. So is there a patch coming or what ? Lastly, Elite 2 works fine with mega-em, although with no sound effects. Rock on people, Ivar Frolich ------------------------------ Date: Fri, 5 Nov 1993 02:37:26 -0800 (PST) From: Ganja farmer Subject: Re: GUS Daily Digest V8 #5 Hey all! With all this talk about 2nd Reality demo and Terminator Rampage, I was gnawing at the bit to try them myself. However, I have been unable to find either of them, and I don't know their filenames, so archie is really not working too well for me. If anyone could _please_ tell me where to find them; I've looked at wuarchive, ftp.uml., cs.uwp., nic.funet., etc. but still can't. Argh. Many thanks in advance! chris yaga@u.washington.edu ------------------------------ Date: Fri, 5 Nov 1993 20:46:17 -1000 (GMT-10:00) From: Paul Murgatroyd Subject: Re: GUS Daily Digest V8 #5 > For some silly reason, DRAM chips are specified in "KilioBITS", not > "KiloBYTES". 256 KilioBITs is actually 32 Kiliobytes (8 bits/byte). 256Kx4 > means 256 Kilobits times 4, which works out to 32 kiliobytes times 4. > This means that for each single DRAM chip there is 128 Kilobytes. Hmmmm....just read the explanation from all your more educated folks, and now I am more enlightened on the subject. Still, the method I describe above is how I was taught about DRAMs and EPROMs etc, back when I did some work for my father's company programming all the EPROMs for the blood analysis machines and the likes. I guess it doesn't matter which way you do it, as long as you get the right answer every time :-) ------------------------------ Date: 5 Nov 93 08:44:00 EST From: "VULCAN::WATTERS_C" Subject: Re: GUS Daily Digest V8 #5 >Now, what I'm wondering is, if these guys are planning for the future, >than what the hell are they doing writing software which "... writes >directly to the FM chips...".

Return to Zork specifically mentions AIL drivers in the docset, it doesn't really give you instructions on how to install them, but it does say that if your sound boards doesn't have drivers supplied by Mediagenic/Activision/ Infocom, you should be able to install any AIL drivers for your board and get it to work. ------------------------------ Date: Sat, 06 Nov 93 00:34:50 EST From: BGUZ000 Subject: where is mega-h.zip I read in the digest that there was a time extender for Mega-em located at epas. For some reason I can not find it. Could someone please tell me exactly where it is located. Thank You ------------------------------ Date: Fri, 5 Nov 93 11:46:22 CST From: Han-jung Kim Subject: Where is mega-h.zip??? Phat wrote a patch of megaem 20 min limit is on epas. But could not locate it although I roamed away here and there. Even the Index.ALL does not show mega-h.zip. Woul any one locate this file for me? I sent an email to Jayeson to release on version without the time limit and he told that the program was already reconfigured and not too easy to remove the time part and also new version would not be released too much far off. However I want to use the current version of megaem over 20 min and need the hack right now!!! thanks. ------------------------------ End of GUS Daily Digest V8 #6 ****************************** To post to tomorrow's digest: To (un)subscribe or get help: To contact a human (last resort): FTP sites: archive.epas.utoronto.ca /pub/pc/ultrasound wuarchive.wustl.edu /systems/msdos/ultrasound archive.orst.edu /pub/packages/gravis theoris.rz.uni-konstanz.de /pub/sound/gus FTP mail server: mail-server@nike.rz.uni-konstanz.de Hints: - Get the FAQ from the FTP sites or the request server. - Mail to for info about other GUS related mailing lists (programmers, musicians, etc.).
