Acero" Subject: Re: Adaptec 1542C, GUS and Falcon3 Message-ID: I have an Adaptec 1452C and a GUS, and I was having a similar problem with Strike Command. It appears that some games are too aggressive when they search for a sound card. The fix, in my case, was to answer 'no' to 'automatically detect sound card', and to install it manually. I don't know if that will work for you.

Urp...that explains a LOT of weird things I've heard!! The chris*.mid files in particular use a lot of channels for chorus and echo effects. On a separate subject, probably a FAQ, is there a simple way to enable the Line In so I can listen to audio CD's from *DOS*? The Windows driver (or somebody) disables it when exiting Windows: the CD keeps playing but the sound cuts off. I have a DOS utility similar to WinCD Pro to play the things but it doesn't have a clue how to enable the audio pass-through. (Yeah, I know I could write a utility to do it but I have to draw the line SOMEWHERE!) ------------------------------ Date: Thu, 22 Jul 93 12:27:35 -0400 From: David D'Antonio Subject: Re: NMI stuff Message-ID: <9307221627.AA05683@magick.tay2.dec.com> Sam Mertens writes: (note that mail to you bounced) > It seems that NMI was set up at a time when RAM was much less reliable > than it is now.

Memory CONTROLLERS, yes, but not the actual RAM). As a matter of fact, my brother's machine has had an entire 4MB bank go bad. He thinks it was due to heat, in that the power supply fan was erratic...So it DOES happen... > The operating principle behind NMI is a parity check - memory is > physically addressed by a row and grid method, so the computer adds up all > the 1s and 0s in each row, and the parity for that row is set to a number > (0 or 1) that when added to the row's sum, will result in either an 'even' > number or an 'odd' number...

The system then, of course, goes back to check Parity is rather simple. Each 8-bit byte as an extra bit devoted to parity (hence the 9-chip SIMM [1 bit per chip] and the 3-chip SIMM [1 nibble per SIMM with an extra 1 bit chip]). The number of 1's in this byte is added and the parity bit is set to make that number 'even' or 'odd' depending on the parity scheme. It's pretty good (it takes flipping 2 bits to have the parity bit not change so this method will catch 1-bit errors). There are much better methods available, but they tend to require either more processor intervention and/or more bits to make them work (Hamming codes are popular because they can detect and CORRECT errors)... As far as I understand it, NMI stands for Non-Maskable Interrupt and it is usually devoted to memory parity. However, it can be handled by someone other than the system (SBOS in this case). I think what happens is that the game writes to the SoundBlaster port, gets an error (after all, the port isn't there!) which triggers an NMI. SBOS traps the NMI and if it's for the SB ports, it handles it, otherwise it passes it on...But then, this is only my guess at how it might work...

The zip- file was corrupted. But when I tried from WUARCHIVE the same thing happened. (I used IMAGE :=} for transfer). When I ZIPFIX it, I get a few files, but SBOSDRV.SYS (or the like) is damaged. Any hint? Did that happen to any other? If the file is corrupted (it has only 78 K) could someone be so kind to upload a non-corrupted version?

The GUS Mixer on the v2.06 disks has no control of the CD input on the card, and there is simply an ON-OFF switch for Line-In control. I've recently added a CD-ROM to my system, and I'm trying to get the audio connection to the CD-ROM tied into the GUS. The Line-In, with its simple ON-OFF switch is just too loud in the ON position compared to the .WAV and .MID controls which have volume sliders. I hope there is an applet like my old SB-Pro had that let me adjust all these sources under s/w control. Any help would be appreciated ! - Kirk McFaul ------------------------------ Date: Thu, 22 Jul 93 16:00:42 CDT From: Michael J Stumpf Message-ID: <9307222100.AA10165@tamsun.tamu.edu> To the author of Mega-Em.. I had a rather long message posted to the digest, but it was on that day a week or so back that the digest barfed. This message described why I'm suggesting what I'm suggesting, but here is the long and short of it. Please do not make mega-em crippleware. You are hurting your own market by doing so. If you do make it that, I will never buy it from you. If you don't, I would consider doing so. Maybe it's just me, but I will not purchase a crippled program, partially it's just the way I think. I guess to consolodate most of my thoughts into one statement, How many of you would pay $50 for sbos? I thought so. ------------------------------ Date: (null) From: (null) In addition I have added a /L switch to EMUSET to enable the Ultrasound Line in. Usefull for Sound Blaster owners. There are two other new switches for EMUSET. /CO1 and /CO2. These are designed to allow Mega-Em to be used in conjuction with a real MPU-401 interface. Could be useful for DOS based MIDI sequencers. I have no means to test these, so they may not work. Look for megem09b.zip on ARCHIVE.EPAS.UTORONTO.CA in /PUB/PC/ULTRASOUND/SUBMIT.
