Enhancing the Osborne Executive Enhanced BIOS Version 1.1 According to OCC, their enhanced Osborne Executive BIOS prevents a premature display of BIOS time-out error messages while using printers with internal print buffers. This is only partially true. The delay value, DELAY0, is reset after every timeout to the value you supplied with the new SETUP command, but the initial timeout value remains at five seconds. To change the initial value, I recommend the following steps, using DU-V86 which can be found on the -FOG/EX1.006 disk. Enter DU, logon to a disk containing CPM3.SYS, and get a map of the disk by typing M. A typical map line might be: A0-AF 00 CPM3 .SYS 00 : B0-B1 00 CPM3 .SYS 01 What we really want to know is where on the disk the CPM3.SYS file starts. On this disk it starts with Group A0. The sector we want to change is 5 groups and 7 sectors or 2FH sectors from the start of the CPM3.SYS file, or in this case, it is group A5:07. Enter: GA0;+2F;D to display the sector of interest. CPM3.SYS will probably start at a different location on your disk, substitute the first group listed in the map for the A0 in the above command. The last line of the displayed sector should read: 70 03CD2EE4 C118DF01 3A06E6B7 2008C5CD *.M.dA._.:.f7 .EM* If it doesn't, then you don't have the latest enhanced CPM3.SYS from OCC or you didn't enter the command correctly. Look at the map again and make sure you have found the first entry of CPM3.SYS in the map. If the last line of the displayed sector matches that above then you have found the correct sector. The eighth byte, 01 above, is the byte we want to change. A value of 01 gives a 5 second timeout, I changed mine to 78H to give a 600 second timeout. To do this, enter: CH77,78;W;X DU will update your disk and exit. Reboot the system with the updated disk and verify that the first BIOS timeout error now takes much longer than 5 seconds. If so, you've now fixed the timeout bug! John M. Blalock PO Box 39356 Phoenix, AZ 85069 (602) 993-4604
