Since the Shit-JIS display routine must be located at 0x1243, the linker script file (ldscript) is applied. - Moved the uninitialized variables from the data to the bss section. 2007-03-17T05:30:03Z KATO Takenori kato@FreeBSD.org 2007-03-17T05:30:03Z urn:sha1:8a44b47598b5ebb72d9e1a4fad87b830dd4b7637 - Fixed typos in comment. - Fixed missing initialization of current device number. 2000-08-06T14:35:37Z KATO Takenori kato@FreeBSD.org 2000-08-06T14:35:37Z urn:sha1:c4082e99a440fd985d1fd588a700654d0b78e752 - Fixed comment.

The IPL loads boot0.5 and boot0.5 loads bootblock of a slice. The boot manager stuff was developed by me (kato) with Borland C++, and then, translated into bcc in the ports collection by Nokubi-san. After that, boot0 has been translated into gas with the .code16 directive by Takahashi-san (nyan) and boot0.5 has been rewritten in gas by me.
