Is there anything with Xenix that would cause it to choke on a 486 upgrade in the P70? Even if it didn't, you likely wouldn't see much of a speed increase since some/all of the upgrades, such as the Evergreen Rev-to-486 like I used, require a driver to enable the cache. The only problem I've run into so far is that the driver seems to be conflicting with the use of an XGA-2 at the same time. Otherwise the upgrade, which uses a TI 486SXL2 running at 40mhz, works fine under OS/2 with an IBM SCSI card and 3com NIC card. There are better accelerator options but they require the use of one of the MCA slots, of which there aren't enough of as it is! As for opening the machine, it's pretty simple. Undo the three large slotted screw fasteners (two on the bottom of the case, one in the upper-right corner of the back, beneathe the cover door) and then gently press in on the bottom of the machine, working your way from one side to the other. This will gently unlatch the fingers holding the back panel to the main part of the case.

The McMaster is definately the way to go if you don't mind losing one of the two slots. It'd be faster and you'll get more RAM out of the deal. Good luck finding one at a reasonable price though.

From what I understand, they are pretty sought after. Is this the same TI chip that I referenced earlier? My P70 is still running it's 387 math-co with the TI 486 chip installed. What kind of drive did you put into it? I'm still running the original 121MB drive. OS/2 looks pretty nice with an external monitor connected to the XGA-2 board.

Besides getting the ADF file for each card that is installed, asked for by the reference disk. -----Original Message----- From: owner-classiccmp(a)classiccmp.org [mailto:owner-classiccmp@classiccmp.org]On Behalf Of Boatman on the River of Suck Sent: Tuesday, December 18, 2001 3:27 AM To: Eric Dittman Cc: classiccmp(a)classiccmp.org Subject: Re: New Finds On Mon, 17 Dec 2001, Eric Dittman wrote: You can't just enter the BIOS on a Microchannel machine.
