ISP Information:
An 8-pin serial EEPROM chip available on some SDRAM memory that keeps specific information about a DIMM's size, speed, voltage, drive strength, number of row and column addresses, DIMM manufacturer, and RAM manufacturer. If a motherboard supports SPD, it can set its BIOS automatically based on these settings to achieve maximum compatibility.

The slow connecting computer used oem12.inf when itwas installed.I have found that different computers may end up using differentOEM.infs for the same hardware. I guess it has something to do withhow many OEM.infs are needed. In this case the contents of the inffiles are identical and are also identical with the inf file thatcomes with the latest version of the US Robotics drivers so thereshouldnt be a problem here.This DSR low is another cause for concernI had wondered about this and sent my first modem back; thereplacement did the same. As it is the same with both computers and Ican get a good V92 connection with one of them I cant see that it isthe explanation. What is DSR anyway??It goes ahead and initializes the modem OK, but there are a couple ofcommands (X4 and S0=0) that are sent twice. That in itself is not aproblem, but I have to wonder why it is redundant. Below is where itreally gets confusing. First it shifts DTR port speed from 115,200 to921,600 and starts the initialization all over again. ?????? 05-04-2004 19:59:48.950 - Send: ATDT###Only 3 digits to make a connection??Yep - my ISP supplies the phone line and uses a special number.After all that, it manages to make a good V.92 connection.The system doesn't understand what the modem is saying in response tothe diagnostic commands.Then below, the modem is initialized AGAIN, shifts back to 115,200, andsets up to receive CID and drops the connection.This shows the different .inf file (oem12.inf) used to install themodem. There are many other errors and unknown responses similar to theother log.At this point, I'd suggest you download the latest files from USR forthe 5633 and do a driver update (Control Panel, Modems, Properties,Driver Tab, Update driver button), then browse to the driver files thatyou unzipped from the downloaded file. Get the driver files here.http://www.usr-emea.com/support/s-prod-template.asp?loc=unkg&prod=5633Do that and report back with your results. Good luck.Unfortunately I already have; all the above is with the latestdrivers.As an experiment I moved the modem to an older (Pentium 3 650MHz)computer and installed it there as a first time install using thelatest drivers. It installs as oem6.inf and connects at 33.2 - grrrrr.Thanks for the help so far; any other suggestions?John***IMPORTANT***Please do not reply to effluent@blueyonder.co.ukThis is an antispam address.Please replace effluent with archway.
