Removing the power plug would reset the condition. LEKT/LEJT63A 37609 PCI adapters with Real memory will not function. 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. 38526 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. LEKT/LEJT64A 39798 Fix for Dos Extender Programs giving EMM386 Except Error#12 40911 Applications failing because of earlier change to video mode for monochrome support. This fix for Clearing Screen in Post has been backed out. (37003) LEKT/LEJT65A 41816 Using Space Saver Keyboard, CTRL ALT DEL will now respond. LEKT/LEJT66A Build not done. Library problem. LEKT/LEJT67A 45876 Option ROM signature not found on one IBM token ring card. 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. 51501 Make IRQ 9 available if reserved in ISA legacy screens 52070 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.
