Flash Changes PC 100 (6260) LYJTxxA is the flash diskette level. LYKTxxA is the flash image level. (BIOS) NOTE: All changes carry forward. That is, if a change is added in 7, it is also in 8, 9, etc... --------------------------------------------------------------------------- Changes for LYKT/LYJT14A 05/07/96 * Intial release of code to manufacturing --------------------------------------------------------------------------- Changes for LYKT/LYJT15A 05/08/96 (Note: This level was only released for internal IBM testing) * Fix problem with Parallel Port in ECP mode using DMA3. * Added code to support Fast Page mode memory SIMMS. --------------------------------------------------------------------------- Changes for LYKT/LYJT16A 05/10/96 (Note: This level was only released for internal IBM testing) * Fix serial port dropping characters at slow (300-2400 BPS) data rates. Note: This problem would only be encountered with communications programs that use BIOS calls to access the serial ports. Most current operating systems (OS/2, Windows95, Windows 3.1) use device drivers to access the serial ports and would not be affected by this problem. --------------------------------------------------------------------------- Changes for LYKT/LYJT17A 05/28/96 * Change parallel port EPP mode from EPP version 1.9 support to EPP version 1.7 support. (This was done so that serial devices that follow the 1.7 standard will work with this system. Devices that support the 1.9 standard will also work with a system that uses the 1.7 standard.) --------------------------------------------------------------------------- Changes for LYKT/LYJT18A 05/31/96 * Fix intermittant diskette failures after power up --------------------------------------------------------------------------- Changes for LYKT/LYJT19A 06/11/96 * Fix video code to correct intermittant hang (blank screen, no cursor) during POST after power on. * Corrected error in levels 16 thru 18 that caused the Setup diskette to fail to load the translated versions of the setup program correctly. --------------------------------------------------------------------------- Changes for LYKT/LYJT20A 06/14/96 * Fix problem with IBM logo distorted or not displayed when using a Matrox Mellinium video card. --------------------------------------------------------------------------- Changes for LYKT/LYJT21A 08/28/96 * Fix hang when attempting to RIPL (remote initial program load) using a 3COM ISA Ethernet III Combo adapter card. --------------------------------------------------------------------------- Changes for LYKT/LYJT22A 10/04/96 * Never released. --------------------------------------------------------------------------- Changes for LYKT/LYJT23A 10/10/96 * Fix hang problem encountered when PCI busmaster cards (Lan adapters and some SCSI adapters) are used with async. L2 cache. --------------------------------------------------------------------------- Changes for LYKT/LYJT24A 10/17/96 * Correct problems with detection and timings of EDO memory --------------------------------------------------------------------------- Changes for LYKT/LYJT28A 02/18/97 * Incorrect characters displayed when Spanish language selected.
