I received a list of EISA boards from AST last week, and I thought that I would share it with the net. Which of these items come with Unix drivers is not specified, but the product list with phone numbers should prove imminently useful for those who custom-build or hack their own systems. If anyone out there knows what Unix/Xenix drivers are available for these boards, please let me know and I will re-publish this list, showing which boards come with drivers for which versions. All products listed are supposed to be currently shipping. All these boards are 32-bit boards. Nearly all the boards listed indicate bus mastering capabilities. The absence of a "Yes" under the "Bus Master" column merely notes that bus mastering capabilities were not specified on AST's list. I have double-checked the phone numbers with AST's list. I can assure you that the phone numbers are only as accurate as AST has provided them. Good luck.

I must say my first expreience with an EISA system has been a nightmare, and the perceived improvements certainly don't outweigh the pain. HARDWARE: ALR PowerCache 4e (486) 600Meg disk, 24 Meg RAM, Corollory 8x4 multiplexed serial board (32 ports), Western Digital EtherPlus 16. Wangtek 150Meg Tape SOFTWARE: ESIX Rev D PROBLEM: The systems (two identical ones) crash sporadically when reading or writing the tape drives. Sometimes it works fine, sometimes it causes kernel panics (the lovely kind that try to dump system RAM into swap). The problem was not repeatable at will, but frequent enough to make the systems useless for their intended applications. SOLUTION: Moving the Wangtek tape controllers from EISA slots to the 16-bit ISA "compatability" slots resolved that problem. The tapes now work just fine. SIDE-EFFECT: Now the system panics sometimes, with the same error messages, when reading from or writing to ... the floppy! If indeed the EISA slots are supposed to, by definition, be backwards compatible with ISA slots, why would moving a board from an EISA slot to an ISA slot change the machine's behavior? Or is this a "standard" that each manufacturer implements differently? :-( -- Evan Leibovitch, Sound Software, located in beautiful Brampton, Ontario evan@telly.on.ca / uunet!attcan!telly!evan / (416) 452-0504 Keep an open mind -- you'll never know what might fall in.

If you all thought I was screaming because of the recommendations of EISA over MCA I got. You ain't seen nothing, if I would have gone EISA (haven't bought the system yet) over MCA and something like this would have happened, I would have screamed a hell of a lot more. :) Such behavior is no where near acceptable for a Unix box. Of course, WangTek tape drives (save their DAT's) aren't that great of a machine. I remember adding one to a customer's Sun SPARCstation 1+ and it never quite did work 100% of the time. Finally, it died completely a couple of weeks ago. I called up MicroNet for the RMA and found out they don't bundle WangTek tape drives with their storage systems anymore. Too many problems with them. So I ended up replacing the WangTek with what MicroNet supports now; a Tandberg. Never had a problem with it again. Since MicroNet hasn't given me anything but acceptable service for me and my customers, I will side with them on matters concerning the reliability of a given manufacturer. // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | What to buy? ** ARPANET : crash!pnet01!jca@nosc.mil | EISA or MCA? ** INTERNET: jca@pnet01.cts.com | When will the bus wars end? ** UUCP : {nosc ucsd hplabs!hp-sdd}!crash!pnet01!jca **--------------------------------------------------------------------------* */

Some things to remember with EISA at this time: 1. It is fairly new, so there may be problems with some implementations (the same kinds of problems that exist with some ISA implementations). 2. Most OSs have not yet been tested/modified to work correctly with EISA (don't know if this is true for ESIX, but ISC2.2 requires a fix disk to work correctly with EISA). I'm not saying EISA is "the" way to go, just that like any new toy, you can't expect to run at the cutting edge of technology and not experience some problems. >Such behavior is no where near acceptable for a Unix box. Yup. But if the Unix vendor does not say thier product will work with an EISA board, you are on your own. The same goes for unknown ISA boards. >Of course, WangTek tape drives (save their DAT's) aren't that great of a >machine.

Finally, it died completely a couple Oh my god, the VME bus must be the problem (if they still use VME?) :-) (this is what you sound like when you sound off about EISA with the slightest hint that someone had a problem.) -- Conor P.

Actually, no, I may consider EISA, but I want to eliminate all potential problems before they happen. One of which, I don't want to be a lab rat for X's implementation of EISA on Y's flavor of Unix. >Some things to remember with EISA at this time: > > 1. It is fairly new, so there may be problems with some > implementations (the same kinds of problems that exist with > some ISA implementations). The main problem is that with the new wave of EISA machines is that you are going to be a lab rat. Why be a lab rat? Also, the problems with ISA have been, for the most part, ironed out. > 2. Most OSs have not yet been tested/modified to work correctly with > EISA (don't know if this is true for ESIX, but ISC2.2 requires > a fix disk to work correctly with EISA). True, but shouldn't EISA be backwards compatable to ISA? Put the EISA slots in ISA mode and they should work fine, right? Well, they don't seem to, do they? The one problem that I have is that the problem machine posted is an ALR PowerCache 4e which is Novell and SCO certified. Ok, barring that in mind, if you don't take advantage of the special capabilities of EISA, your ISA cards should work fine, right? Wrong, this poor soul's tape drive controller bombs his system. >I'm not saying EISA is "the" way to go, just that like any new toy, you can't >expect to run at the cutting edge of technology and not experience some >problems. > >>Such behavior is no where near acceptable for a Unix box. > >Yup. But if the Unix vendor does not say thier product will work with >an EISA board, you are on your own. The same goes for unknown ISA boards. I read between the lines on that statement. If a vendor doesn't support EISA, I read that to be "our product doesn't support the full capabilities of the EISA bus." All of the EISA hype is that it is backwards compatable with ISA, correct? And this isn't some generic EISA board, but from a major 80x86 system vendor that has the seal of approval from Novell and SCO. Should work, based on all of what EISA is supposed to do. Enough of the third degree. Do you now see my point about why one should be weary of EISA and why I am seriously considering MCA as opposed to EISA? EISA may be just perfect for someone else, but I don't want to be a lab rat. Why be a lab rat when I can get a 386 or 486 machine with a system bus that has seen the light of day longer than EISA? I will admit that the tape drive controller may not be the problem with the Powercache 4e and the WangTek tape controller, but it looks awfully suspicious to me when the controller is pulled out of the EISA slot and works better in the ISA slot. The only real way to isolate if it's the Powercache's EISA bus is to build an identical system on an ISA machine. If it works on the ISA machine, then you know it's the EISA bus on the Powercache. // JCA /* **--------------------------------------------------------------------------* ** Flames : /dev/null | What to buy? ** ARPANET : crash!pnet01!jca@nosc.mil | EISA or MCA? ** INTERNET: jca@pnet01.cts.com | When will the bus wars end? ** UUCP : {nosc ucsd hplabs!hp-sdd}!crash!pnet01!jca **--------------------------------------------------------------------------* */

I don't know what your dataset is (more than the one machine I assume), we have about 400 Suns, with maybe 100 tape equipped. My buddy who sells database applications with a server bundled likes them, and he may have to fly a thousand miles to install a new one in some cases. I can't compare with anything in quantity, but they have always been good to me. -- bill davidsen - davidsen@sixhub.uucp (uunet!crdgw1!sixhub!davidsen) sysop *IX BBS and Public Access UNIX moderator of comp.binaries.ibm.pc and 80386 mailing list "Stupidity, like virtue, is its own reward" -me
