This device drive will query the bus for any CM250 or CM260 interface boards. upon finding the boards it will determine if there are any conflicts with the IRQ or port address settings. If there is a conflict it will report "No drives found". The driver will support any combination of CM205 and CM206 drives. The device driver named ddlms.add will support: A CM250 8-bit HA with a CM205 1X drive A CM250 8-bit HA with a CM206 2X drive (the HA can't stand 2X, so it will hold the drive in 1X) A CM260 16-bit HA with a CM205 1X drive A CM260 16-bit HA with a CM206 2X drive The config.sys lines to add are: DEVICE=C:\OS2\OS2CDROM.DMD /V IFS=C:\OS2\CDFS.IFS /V basedev=lms206.add /u:0 /m:26 /v (Device driver statement for drive 0) basedev=lms206.add /u:1 /m:26 /v (Device driver statement for drive 1 assuming that you have more than one drive) Description of command line: basedev=lms206.add /u:N /m:B /v where N is the unit identifier 0, 1, 2, or 3, and B is the number of sector buffers to provide for pre-read cacheing (26 max.) /v causes two lines to be displayed at boot up: IBM OS2 DDLMS.ADD 1.00 27-OCT-93 Philips LMS Unit N: CM20X CDROM drive, FRX, CM2X0 HA Port: 03X0 IRQ: XX FRX is firmware revision X (0 - 7, current is 4) CM20X and CM2X0 may have either 5 or 6 as X. Port: X = 0, 1, 3, 4 for CM250; X = 0 - 7 for CM260. IRQ: XX = 3, 4, 5, 6 for CM250 XX = 3, 4, 5, 6, 9, 10, 11, 12, 15 for CM260 IF YOU OMIT /u:N WE WILL DEFAULT TO 0. IF YOU OMIT /m:B WE WILL DEFAULT TO 16. IF YOU OMIT /v WE WILL SHUT UP AT BOOT TIME. ****************************************************************
