Спасибо за помощь :) Стыдно, конечно - на любимом

Option syntax Meaning
-a Perform the operation on all the Matrox cards in the system. When not used, the PROGBIOS will use only the first board it can find.
-b ,,
<1stbyte>,... Patch BIOS image. No spaces allowed in arg string. All numbers are in DECIMAL.
- the adress for start of a patch. May be either number or one of the following strings:
"SUBSYS_VID" (=7FF8), "SUBSYS_ID" (=7FFA),
"PINS", "PINS+", "SYS_ID", "OPTION"
- no. of bytes to patch.
<1stbyte>.. can be either the new byte value, "OR_" or "AND_. OR and AND seem not to work properly(?).
G100 patch supplied by Matrox calls “PROGBIOS –b subsys_id,2,1,255” – this allows for proper recognition of G100 by some versions of drivers.
-d Dump PINS to console. You should invoke “PROGBIOS –d >mypins.txt” before trying to program the BIOS for the first time.
-e ??? Has something to do with “emergency file”. Seems it is not working properly...

-font ??? Usage: PROGBIOS -i -font -o . Update VGA font image in BIOS ???.
-i
-i auto Program BIOS from file (select the file automatically from current directory if AUTO used). Note that the PINS is read from old BIOS, updated and combined into the new image of BIOS. "auto" sometimes doesn't work correctly with PROGBIOS above 1.73.
-k Force programming even if old BIOS checksum error occurs (but not PINS error). Doesn't work properly in PROGBIOS above 1.73 !!!
-k1 ??? (My guess: force programming anyway.)
-maven sets the output mode for MAVEN (TV interface chip). may be one of the following:
off - turns TV out off
ntsc,ccomp - NTSC composite output on RCA connector
ntsc,scomp - NTSC composite on SVIDEO
ntsc,srgb - NTSC RGB out on SVIDEO
pal,ccomp - as above, but PAL
pal,scomp
pal,srgb
-o Don’t program the BIOS, create BIOS image and save it in file.
-r ??? Used only with both –i and –o.
-s Get PINS from text file (instead of card’s BIOS). The file has the format identical to that created using –d option, so when the BIOS dies completely, “-s mypins.txt” can be used to revive it. Can be combined with -i and “-i -o”
-sync Sets the sync output mode. may be one of the following:
csyncgreen
sephv
sepcsync
-tv ??? TV output???
-v Show PROGBIOS version/build info.
