What the 701 really needs is some L2 cache. I had the chance to see my
701 run side-by-side with an AST 486DX/75 with L2 cache. As far as I
could tell the only differences were the 701 had 24MB RAM and no L2,
the AST had 16MB RAM and L2. I wasn't able to run any quantifiable
tests but for the task being run the AST was sprinting and the 701 was
out for a Sunday morning jog. Oh well, the 701 is slicker looking!

It appears that more people are using NT on their 701 than I thought. Just a
remark. But I also run NT Server 4.0 on my 701C with 40MB (8+32) of memory. I
notice that PCMCIA cards are temperamental in NT. The interrupt that a card
uses is determined by NT's PCMCIA driver (I think) at boot time and can't be
changed. For example, I have an IBM Token Ring Auto 4/16 PCMCIA and it would
change from Int 5 to Int 10 depending what other card I have and which slot the
token ring card is in. So my driver would sometimes not load if I switch the
slot or change a card. In your case, I would boot NT with the modem in, and
check in the Control Panel/PCMCIA and find out what interrupt and etc it uses
then install the driver for the modem with that setting (if it needs a driver).
And if it doesn't have a driver, try to disable one of the serial ports in BIOS
setup (COM1 or COM2) and see if that helps. I don't know exactly how NT will
make the card a serial port but I know that the PCMCIA driver will not use Int
3 or 4 if the built-in comm ports are on.
Regarding improvement in performance with the memory, in my case, it improved
the responsiveness dramatically from 24MB. Overall the system is faster too if
the application is more memory dependant than processor dependant. I would
recommend the upgrade. I do have a 1.44GB IBM drive instead of the factory 540MB
which could also affect the performance a little. But I think the CPU needs to
upgraded before the 701C can be an ideal mobile workstation. 486-75 is just not
enough for CPU intensive apps. I've looked into the AMD 586-133 upgrade(about
$400) but haven't heard any good news from any users (I don't trust ads). Btw,
my 32MB module cost me about $300 I think.

Subject: TP 701 Memory & Modem Difficulties
I just installed a 32MB memory module into my 701, which means I
can use the 16MB module as a tooth pick or sell it. It's a IBM
P/N:92G7263, 16MB 70ns 3.3V Non-parity. I've been using it for about
one year with out difficulties and it has about two of the three years
lefton the warranty. Any one interested send email to rj@cais.com with
a reasonable offer and we'll work out the details.
Now for the modem part of the post. I just got a Hayes Accura 56K PC
Card modem and I can not get it to work worth a darn. I called Hays and
and they said they don't support NT 4.0. However, many of their customers
are running NT and some portion of this group got the modem functioning,
or so they said! But they wouldn't discuss it because they don't support
NT. Wird! And yes I know its not a wird as running NT on a 701 (which BTW
was the reason for the memory upgrade, and it has helped). Has anyone on
the list any ideas on how to get this modem to work correctly?
Thanks in advance!
