Date : Wed, 10 Nov 1982 02:54:29 EST (Wed) From : Ben Goldfarb <goldfarb.ucf-cs@Udel-Relay> Subject: Re: CP/M disk logins The BDOS asks the BIOS to log in a disk by passing a flag in the E register when calling SELDSK. As to how the BDOS knows that a log in is necessary, I can only surmise that the directory checksum is verified before any disk write, but I have nothing with which to back that up. Ben Goldfarb
