I have run INFOPLUS 1.40 on a friend's PS/2 model 70. I found many
abnormalities on the CMOS page, including a checksum error and no
hard disk indicated. At first, I suspected that someone may have
tampered with the machine, but now I am wondering if the format for
the CMOS that INFOPLUS appears to be using (correct for AT) is
correct for PS/2. Could someone tell me the format of the PS/2
(Model 70) CMOS is (if it indeed differs from AT)?
BTW, I have run the automatic setup from the configuration disk,
which looks correct for the machine.
For additional info, here is the dump of the CMOS contents:
00 01 02 03 04 05 06 07 08 09 0a 0b 0c 0d 0e 0f

The machine is a PS/2 model 70 with 5M memory, 60M ESDI harddisk,
two 3.5 1.44M floppies, and 1 parallel, 1 serial, and 1 mouse port.
While most of the configuration is correct (according to AT format),
byte 12h is incorrect (harddrive = 00h, none installed) and bytes
after 09h are inconsistent with the AT format.
Thank you for any info or assistance you can provide!
