This capability means that up to four operating systems ! 15: can be supported on one hard disk. ffddiisskk recognizes the ! 16: following flags: ! 17: ! 18: -rr Read-only access to partitioning information. ! 19: ! 20: -bb Use the first 446 bytes of _m_b_o_o_t as master boot code to ! 21: replace that in _x_d_e_v. ! 22: ! 23: -cc Allow the specification of disk geometry (i.e., number of ! 24: cylinders, heads, sectors) for disk drives that are not ! 25: supported by the system BIOS. ! 26: ! 27: ffddiisskk accesses the first block from the special device _x_d_e_v ! 28: (e.g., /dev/at0x) for the partitioning information. ffddiisskk then ! 29: queries the user for changes. These changes are written to _x_d_e_v ! 30: only if the user requests the changes to be saved. If omitted, ! 31: _x_d_e_v defaults to /ddeevv/aatt00xx and /ddeevv/aatt11xx. SCSI disk device users ! 32: will need to specify _x_d_e_v as /ddeevv/ssdd_nxx where _n is a digit ! 33: corresponding to the SCSI ID for the disk device (e.g., ! 34: /ddeevv/ssdd00xx). ! 35: ! 36: ***** Files ***** ! 37: ! 38: <ffddiisskk.hh> ! 39: ! 40: ***** See Also ***** ! 41: ! 42: ccoommmmaannddss ! 43: ! 44: ***** NNootteess ***** ! 45: ! 46: IIff tthhee ppaarrttiittiioonn ttaabbllee iiss cchhaannggeedd, tthhee ssyysstteemm sshhoouulldd bbee rreebbooootteedd; ! 47: mmoosstt ddeevviiccee ddrriivveerrss wwiillll nnoott rreeccooggnniizzee tthhee rreevviisseedd ppaarrttiittiioonn ! 48: iinnffoorrmmaattiioonn uunnttiill aa rreebboooott ooccccuurrss. ! 49: ! 50: AAss tthhee -rr and -bb options are contradictory, attempting to use ! 51: them together generates an error message. ! 52: ! 53: Please note that some versions of ffddiisskk for other operating ! 54: systems can rearrange the order of entries in the partition ! 55: table. If this happens, you may lose the ability to run COHERENT ! 56: until the table is restored to its previous order. A sign of ! 57: this problem is getting the prompt AATT bboooott? when trying to start ! 58: COHERENT after running any ffddiisskk program, and not being able to ! 59: get past it. ! 60: ! 61: ! 62: ! 63: ! 64: COHERENT Lexicon Page 1 ! 65: ! 66: ! 67: ! 68: ! 69: fdisk Command fdisk ! 70: ! 71: ! 72: ! 73: Computer systems that use older BIOS releases may report ! 74: incorrect disk parameters. Users of such systems should change ! 75: the CMOS setup values if possible, but the BIOS on some older ! 76: systems will not allow you to specify arbitrary values for disk ! 77: parameters. Users with such systems can use the ffddiisskk -cc option ! 78: instead. ! 79: ! 80: If you plan to install and run COHERENT and MS-DOS on the same ! 81: hard disk, note the following: ! 82: ! 83: -> If you wish to install COHERENT and MS-DOS on the same hard ! 84: drive, you _m_u_s_t run the MS-DOS ffddiisskk first! ! 85: ! 86: -> If you plan on running both operating systems, you _m_u_s_t ! 87: install MS-DOS first and leave some free cylinders on the ! 88: disk for COHERENT as well as a free partition. You can have ! 89: both primary as well as extended MS-DOS partitions on the ! 90: same drive as COHERENT, but COHERENT cannot use a sub- ! 91: partition of the MS-DOS extended partition. COHERENT must ! 92: have one of the four _r_e_a_l partitions. ! 93: ! 94: _F_a_i_l_u_r_e _t_o _o_b_s_e_r_v_e _t_h_e_s_e _r_u_l_e_s _w_i_l_l _r_e_s_u_l_t _i_n _l_o_s_s _o_f _d_a_t_a ! 95: ! 96: ! 97: ! 98: ! 99: ! 100: ! 101: ! 102: ! 103: ! 104: ! 105: ! 106: ! 107: ! 108: ! 109: ! 110: ! 111: ! 112: ! 113: ! 114: ! 115: ! 116: ! 117: ! 118: ! 119: ! 120: ! 121: ! 122: ! 123: ! 124: ! 125: ! 126: ! 127: ! 128: ! 129: ! 130: COHERENT Lexicon Page 2 ! 131: ! 132:
