Agree ! Factory Translated specs are 903 cyl, 4 hds, 46 sect/track, write precomp 0, LZ 903. It may have been setup with a disk manager type software so the settings on the label is diff than factory translated. Ohh those hand labeled specs are for a CP30080/84 not the CP30084E as on the Conner …

Well "Compatibility : Adlib, SoundBlaster 2.0, SoundBlaster Pro" does not mean Wavetable lol According to the ESS Maestro-2 datasheet page 15 and 16 there is charts where PCI register porting shows it might allow Midi port 330 be synthed thru the DOS SB Pro FM emulation. Page 1 say: "features …

Hmm Opti 931 PnP card. When you say "entering MS-DOS mode" are you referring to WIn98 DOS Window or exiting to DOS. Have you tried F8 booting to DOS 7 and run SNDINIT.EXE ?

I would try the external 4.5v first, that would rule out a board issue if it works. A rare few old boards had a 4.5v rechargeable not the 3.7v. Trying the 4.5v external will help find out as those boards needed 6v external (more diodes from the external pins to actual cmos battery traces). A 3.6v …

What voltage was the old Varta ? Many of the old 286, 386 used a 4.5v external if the 3.7v Varta was removed. The CR2032 may not be supplying enough voltage.....

Being a rev 2.3 it will not support MMX (no 2.8v core support like rev 3.x) see: http://web.archive.org/web/19970607091346/http://www.asus.com/products/techref/mb/p55t2p4-tech.asp That page also gives some Cache module info.

Yes could be a HD boot virus they were common back in the day or the old HD is dieing (or is it dying). There were many old "root" variant virus back in the 90's that could make a mess of a HD.

Am not a guru on some of the ESS chipsets (because they changed a bunch over time) but in your DOS autoexec.bat do you have a C:\maestro.com or LH c:\maestro.com (depending on your memory config) as the first line ? Also may require a Set Blaster= line but not sure as that changed from one ESS …

Great reference ! The important parts have to do with Voltage compatibilty. You can blow a board or card by running a wrong voltage compat AGP card in a boards AGP slot. I do not solely trust the slot type but use it as a guide and then read the Vid card and mobo's spec to make sure they can work …

Sounds like improper DOS drivers where in DOS MODE thru Windows they work fine due to Windows drivers. Read this: ESS (not Ensoniq) Maestro-2 Compatibility it may help. Then if you go here: http://web.archive.org/web/20030207160318/http://www.esstech.com/techsupp/drivers.shtm#pci or http://web. …

Wow that is odd. Maybe the epoxy on the DIE cover was weak on that particular Celeron or could the core/die still have been warm when removed ? Most epoxies get weaker when hot. Glad you warned us ! I still use cheap white thermal grease for testing, easy to clean off but have considered thermal …

Should be a good card ! Price may seem a bit high but if includes shipping then is actually good price. Jumper Set SB16 cards do cost more than the PnP later versions where I live and it makes sense. The PnP types will not work on a 286 (ok maybe if you fiddle fart around enough) and rarely work on …
