A 'show modules' will give you the info:
Here's a bi8k with M4 modules:
Module Status Ports Starting MAC
S1: B4GMR4 M4 Management Module, SYSIF 2 M4, ACTIV 4 0004.8048.6e00
S2: B4GMR4 M4 Management Module, SYSIF 2 M4, STAND 4 0004.8048.6e20
S3: B8G Fiber Switch Module, SYSIF 2 OK 8 0004.8048.6e40
S4: B8G Fiber Switch Module, SYSIF 2 OK 8 0004.8048.6e60
Here's a bi8k with Jetcore Modules:
Module Status Ports Starting MAC
S1: J-BxGMR4 JetCore Management Module, SY M4, ACTIV 8 000c.db48.9300
S2: J-BxGMR4 JetCore Management Module, SY M4, STAND 8 000c.db48.9320
S3: J-BxG JetCore Gig Fiber Module, SYSIF OK 8 000c.db48.9340
S4: J-BxG JetCore Gig Fiber Module, SYSIF OK 8 000c.db48.9300
S5: J-BxG JetCore Gig Fiber Module, SYSIF OK 8 000c.db48.9300
S6:
S7: J-B48E-A JetCore Copper E Module, SYSI OK 48 000c.db48.9300
