and any other that require IRQ 2.
N2KT/N2JT39
36951 Force color palette loading if passthru adapter installed
36976 Suspend/Resume fails with certain CDROM drives

38345 POST hangs with XGA-2 installed in non-US countries
N2KT/N2JT42
37791 Drives on secondary controller may falsely report not busy
and therefore not be recognized during POST.
37792 Int 15 Function E820 returns incorrect values if EBDA was moved by
The operating system. No known problems have been encountered.
38527 Change stack pointer during int. 19 to prevent stack overflows.
Some PCI SCSI adapters were overlaying the stack and causing various
errors including hangs during POST.
38564 Add changes.new and readme.1st files to flash diskette. This will
allow the users to see what changes have been made in
order to determine if they need to upgrade their systems.
38814 Clear cmos byte 5f if cmos corrupt. This could have caused unread-able
screens after a bad battery.
38669 PCI Adapter take MicroChannel space when 64k buffer defined. This
shows up if a token ring card uses a 64k buffer. The PCI card
took the same memory. This should have caused an 1801 error because
the memory was not available. The error will now appear in this
scenario.
38545 Memory dump system reset always causes POST error 210. This only
occurred if Stand Alone Dump for OS/2 2.11 was taken.
N2KT/N2JT43
39036 Update video BIOS to correct cursor problem when using Windows at
1024X768X8 at 72Hz.
N2KT/N2JT44
39324 Fix intermittant 201 (memory parity) errors. (No customer reported
problems - only seen in manufacturing test.)
N2KT/N2JT45
41045 Fix hang during warmboot with LANStreamer MCA card. This could fail
with any busmaster MCA card. Reset MCA channel before ROM shadowing.
40243 Microchannel reset timing incorrect. No known problems caused by this.
This corrects the length of the reset to meet specifications.
39559 162/184 config error. Intermittant configuration errors occur even with
no changes. This was found on another system and has not been reported
on this system.
39353 Some PCI video cards may conflict with other PCI devices. This was reported
on another system. No known problems on this system.
N2KT/N2JT46
42094 Fix century byte location to match other micro channel systems. This
corrects incorrect date on WIN/NT.
43691 Cache line size may be set incorrectly on some PCI adapters
N2KT/N2JT47
50491 Some installations get EMM386 Exception Error #12
49383 1762 error after adding 6X or 8X CDROM Drives. The problem is an error
in the chipset on the drive. However, we will change the detection
code to get around the chip problem. This only fails on drives with
one vendors chipset.
50944 Matrox PG2-1281 does not work. No video from either the planar or
Adapter.
1762 error after adding 6X or 8X CDROM Drives. This corrects a problem
that caused the drives to hang when they were attached as a slave, or
would also hang a hard disk if it was attached as a slave to one of
these drives. This failure only occurred with certain combination of
CDROM drives and certain hardfiles.
N2KT/N2JT48A
Update the flash utility for manufacturing. No other changes in this level.
N2KT/N2JT49A
LPT3 fails after APM events when using WIN/95.
Test programs checking "Year 2000" under DOS could fail even though
the clock updated correctly.
110 errors in POST with memory installed in all slots and Intel
P54CTB upgrade processor installed.
N2KT/N2JT50A
Update century byte in location 37h as well as 32h. Some software is
checking either location. This is a fallback to PS/2 architecture.
